Laura Irene "Laurie" Forman (born 1958 ) is a fictional character on the 1998 to 2006 American Fox Broadcasting sitcom That '70s Show. She was originally portrayed by Lisa Robin Kelly and then later by Christina Moore.
Laurie is Eric Forman's manipulative and popular older sister, who initially lives away from home, attending college. Laurie and Eric's father, Red Forman, spoils her and favors her over Eric. Eric and his friends make fun of her for her promiscuous behavior.
Laurie, who has Farrah Fawcett-style wavy blonde hair, is a promiscuous young woman often seen with different men, from her college psychology professor to Eric's friend Michael Kelso, who cheated on his girlfriend Jackie Burkhart. She is an object of sexual fantasy for Fez, whom she marries later in the series so that he can get a green card. Eric, Steven Hyde, and Donna Pinciotti often mock her promiscuity, and Eric several times refers to her as "the devil." In reference to this running gag, Laurie was born with a tail. Jackie hates her and usually refers to her as "a slut", at one point getting into a cat fight with her over Kelso. A bullying tattletale around Eric and sweet with her parents, she often gives her mother Kitty cause for concern, such as when Laurie tries to seduce the local youth minister, Pastor Dave (Kevin McDonald). Despite her disagreeable personality to Eric, she has occasionally showed sympathy toward him, such as when he was traumatized after seeing their parents having sex.
Laurie's parents express belief that she will accidentally become pregnant. Kitty's reason for telling people about Fez and Laurie's marriage is that "I never thought I'd be able to say 'Laurie got married' without adding 'and the baby came early!'". Also, when Red expresses his desire for a grandchild, Kitty remarks that Laurie probably has "a few" secret children. They laugh for a moment and then a serious expression comes to each of their faces. Eric believes that this has already happened (more than once), when he tells Laurie "I'm sure whatever bastard children you've had have been adopted by now" when Laurie says she wants to make up for her past mistakes. Laurie is shown to be (partially) good with kids in "Baby Fever", but it quickly becomes clear that she values material goods more (exchanging her hair-dryer for the baby).
 Season 1Edit
Laurie appeared in a brief, recurring role in Season One. Kelso, despite being in a committed relationship with Jackie, flirted with (and attempted to seduce) Laurie. Laurie rejected his weak advances, but began flirting with him, and the two made out in "A New Hope", beginning their season-long affair. During Season One, Laurie was going to college in another city, and in the finale, she announces that she has flunked out.
 Season 2Edit
In the second season, now living in her parents' (and her brother Eric's) house, Laurie tricked Kelso into cheating on Jackie and soon everyone but Jackie knew. Kelso attempted to end what he had with Laurie multiple times, only to be threatened that if he ended it, she would tell Jackie everything. Then when he tried to end it again, Laurie agreed, as long as he gave her one last kiss, which he did, little did he know Jackie was standing right behind him causing Kelso and Jackie to break up. Before the breakup, Laurie and Jackie became friends, finding common interest in material things, like hair.
 Season 3Edit
During the third season, she was dating Kelso, although they were only seen together making out or leaving the room to "do it." After talking with Red, she discovered what she wanted to do in life and soon enrolled in a beauty school. Kelso retained feelings for Jackie, and the relationship was clearly only sexual. Later, on Valentine's Day, Kelso caught another man leaving Laurie's room. Crushed, Kelso ended the relationship.
 Season 5Edit
During the fifth season, Laurie returned for Thanksgiving and was mentioned to be now living in Chicago and after accidentally letting it slip she hadn't changed her promiscuous ways, she lost her spot as the favorite child. Later in the season, she returned with a supposed new outlook on life, wanting to correct all the mistakes she had made in the past and become closer to Eric and her family. She goes with the gang on the camping trip they take to celebrate graduation and there sleeps with Fez. Fez, threatened with deportation due to his visa expiring, marries her so he can stay in the country and when she shares this with her parents, it causes Red to have a heart attack. Christina Moore as Laurie Forman=== Season 6=== In the sixth season, Fez tries to trick Laurie into "doing it" as he is the only person to date that she has turned down. Meanwhile, Red and Kitty force the two into a divorce but when they start to receive wedding presents (such as a circular saw and a microwave) that they do not want, they decide to give them to her parents and they quickly decide for them that they should stay married so they can keep getting the unwanted presents. Laurie's last appearance was in "Going Mobile". In the sixth season episode I'm Free, Eric jokes that Laurie's absence was due to being in jail before seriously asking where she has been the last two years.
 Seasons 7 and 8Edit
After season six, Laurie was never seen on-screen again but was mentioned in passing many times over the next two seasons. These ranged from explaining what she was doing at that point in time (such as moving to Canada), to her past in Point Place (such as who her godparents are).
Laurie's last screen reference is in the finale, where Kitty, after stating heartfelt reasons why she loved everyone in the room, including telling Donna that she loved her like a daughter, asks "Speaking of daughters... has anyone seen Laurie?" prompting a long laugh from the studio audience.
- After Lisa Robin Kelly left the show in 2003, Laurie was removed entirely from the show and didn't appear for 47 episodes and wasn't mentioned for 43 episodes (though Red made references to having "kids"). Kelso and Laurie broke up off-screen because of Lisa no longer being involved in the show.
- Laurie has only appeared in one scene transition throughout the show, in the fifth season episode Nobody's Fault But Mine (2).
- Lisa Robin Kelly was set to return to the role for the sixth season for 13 episodes and be billed as a regular cast member again. However, she left the show soon after production began and was replaced with Christina Moore. The scenes featuring Laurie in the first episodes of the season were later re-shot and the character appeared in only six episodes, with Christina being billed as a guest star.
