Lana was a childhood friend of Clark Kent. The two shared a mutual attraction for each other throughout their youth. In current comics continuity, Lana found out about Clark's abilities when they were children, after he saved her life. Some of Clark's powers activate for the first time around Lana (when they shared their first kiss it activated Clark's heat vision and when Lana was swept up in a tornado Clark flew for the first time and saved her). Lana is one of the few people who are aware that Superman and Clark Kent are one and the same.
Lana later attended Metropolis University and pursued a degree in Business and became a successful businesswoman.
Years later, Lana eventually got involved with another childhood friend, Pete Ross, and Pete soon proposed to her. Lana was initially reluctant to set a date for the wedding (still pining after Clark) but after an incident with Bizarro and Superman reaffirmed that Clark would never love her the way she loved him, she decided she wanted to marry Pete as soon as possible.  Lana and Pete were married in a small, private ceremony at the Kent's house, with only a few guests (Superman and Lois were busy in Metropolis)  Lana and Pete then settled into a quiet life in Smallville.
Not long after being married, Lana became pregnant, but complications caused the baby to be born premature. She contacted Superman and asked him to take the baby to a more advanced medical facility in Metropolis, carried in a special traveling compartment. Unfortunately, along the way, Superman is attacked by Brainiac, who then was using Doomsday as a host body. After knocking out Superman, Brainiac/Doomsday takes the baby to his lair, intending to use the baby to grow a new body for himself (as Doomsday's body was beginning to reject his mind). Superman managed to defeat the villain and rescue the baby, discovering that as part of the process of preparing him for Brainiac's experiments, the baby had been aged to term. Returning the child to his parents, Lana insisted on naming the baby Clark Peter Ross. 
In 2000, Pete Ross became Lex Luthor's vice presidential running mate in Luthor's bid to become President of the United States, and after the two won, Lana moved to Washington, D.C. Before moving in, Lana had a talk with Superman, promising that she would keep his secret and announcing she had no feelings for him anymore -- she even went so far as to say that her baby was really named after Martha (her maiden name being Clark).
Luthor was forced from his office, and Pete Ross became president (and Lana the First Lady of the United States). Eventually, Lana and Pete separated and divorced due to Lana's dissatisfaction with Pete and her consistent yearning for Clark, and Lana began to attempt to regain Clark's affections, much to the anger of his (now) wife Lois Lane. However, Pete and Lana have recently reunited after Superman saved them from being killed by the villainous Ruin 
Following the fall of Lex Luthor during his most recent attack against Metropolis, the chairmen of LexCorp have finally voted him off of the board. In an exclusive article to the Daily Planet, the board members publicly announced that Lana Lang was to take Luthor's place as chairwoman and CEO of Lexcorp. Lana served as the CEO of Lexcorp for a short while. Her successful run as CEO was brought to and end, when she attempted to use Lexcorp's resources to assist Superman, breaching a contract that specifically stipulated that any Lexcorp employee who knowingly or unknowingly abetted Superman's actions in any way was to be terminated immediately. A hologram of Lex Luthor appeared in her office and promptly fired her. 
Supergirl as Linda Lang
Lana returned to her family home in Smallville to be closer to her ex-husband and son. Lana takes it upon herself to reach out to Supergirl. She offers her advice and friendship. Around the same time, Perry White has been actively pursuing Lana to take over the Business section of The Daily Planet, a position that Lana was afraid to accept, following her bad experience with Lexcorp. Eventually, Lana and Supergirl decide together that Lana will accept the position, and that Supergirl will take on the secret identity of Linda Lang, niece of Lana Lang. Lana now lives in Metropolis with Supergirl, and is working as the editor of the Business section of The Daily Planet.
Lana has some sort of mystery illness that none of the doctors in Metropolis can figure out and Lana has not told Supergirl about her illness. She is seen coughing up blood and has occasional nose-bleeds. At one point she fainted at a party. Eventually, Linda figures out that Lana has been hiding her mystery illness from Linda but is to late. Lana ends up collapsing in the lobby of her apartment building crying blood that is also pouring from her mouth. By the time Linda can get to the hospital, it is too late and Lana has seemingly died. But when Linda goes to see the body, she sees Lana encased in a chrysalis. Lana's condition is somehow the result of her time as the Insect Queen.
In Metropolis, Supergirl is captured when the hospital is engulfed in a massive cocoon and an army of humanoid insects emerge. Once she is freed by Gangbuster, Kara conspires with him and Kimiyo Hoshi to infiltrate the cocoon, rescue the hostages, and find out who is behind the invasion. After being ambushed and knocked out, Kara awakens bound and gagged at the feet of Lana, who has once again reverted back to her Insect Queen form. Insect Queen informs Kara that during her last encounter with Lana, she embedded a piece of her DNA within her in an attempt to repossess her body. The two women engage in a drawn out battle, with Kara eventually expelling the Queen from Lana's body through the use of an advanced Kryptonian machine. After Lana is cured, Kara informs her that she is leaving her home, feeling betrayed by Lana's unwillingness to share her illness. As Kara flies off Lana realizes that with Kara gone she will be alone.
Who is Supergirl?
After the destruction of New Krypton Kara apologized to Lana for her behavior during the Insect Queen event and they reconciled. Kara is having nightmares about the genocide of New Krypton. One night the nightmare quickly turns into her friends and family in hell, telling her she hurts everyone she touches. She wakes up and Lana lets her know that she thinks of Kara as family. Kara tells her she no longer wishes to be Kara Zor-El, but wants to be Linda Lang full time. She says Supergirl is gone too. She even cuts her hair. They go to enjoy some coffee, and Lana asks Kara where she was during the six weeks after the war, but before moving in. She suggests that Linda attend Metropolis University. Doctor Light and Gangbuster are investigating a crash site. The ship opens and reveals a Bizarro Supergirl
Supergirl is ripping Metropolis apart. Jimmy Olsen manages to take a picture of Bizarro Supergirl and send it to the Planet before being subdued. Lana saw the picture and called Kara and is trying to convince her to change into Supergirl and save the day. Cat Grant overhears the conversation and realizes that Lana and Supergirl have a close relationship. Realizing she can't just quit being who she is, Kara changes into her Supergirl costume and flies off to save the day. Meanwhile, Cat is being harassed by the Toyman and finally acknowledges she needs help with her problems, She tells Lana she knows about her relationship with Supergirl and she needs their help.
Later, Lana is on her way to Smallville to spend Christmas with her son little Clark. Meanwhile, Lana and Kara are having a conversation over their cellphones about Cat Grant. Kara told Lana that she doesn't want to help Cat. However, Lana managed to convince an unwilling Supergirl to help Cat. After Kara agreed, both she and Cat went to Arkham Asylum to confront the Toyman and try to find the children they believe he kidnapped. Cat and Supergirl were able to defeat the Dollmaker and his minions and rescue the missing children. Later The Kent's had a Christmas gathering at the farm. Clark, Lois, Lana, Conner, Krypto, and Linda are all there where Lois shows Linda(Kara) the Daily Planet's new headline: The Day I Needed Supergirl, written by Cat Grant. Kara agrees that even though she may not be perfect it's her life and she's happy with it..
Lana and Lois In Credit Check
While Lana and Lois are on their way to work one morning, Lois is telling Lana a funny story about an ugly dog, when Lois spots a lost credit card for a Mr. Kastan Broadway. Lana, spotting a challenge, persuades Lois to track the man down instead of just handing in the card. Chatting to Clark, Lois vents her frustrations. Clark teases his wife, but that only goads her further. As it turns out, Lana's bit of fun has turned into an actual mystery. Kastan exists on paper, but anything prior to six months doesn't exist.

Before they were ejected, Lois had spotted a few clues, a post-it note with the initials K.B and a matchbook from The DeCarlo Theatre. As the duo approach, they see a poster of Jack Marsh, aka, Karstan Broadway! Jack reveals he has a third identity, Nathan Edwards, son to one of the founding fathers of Intergang. To escape 'servitude' to this mafia, Nathan's uncle helped him disappear. Lois agrees not to print the story and even recommends Jack's show for a review.
