The Face of the "Mean Sister" We All Loved to Hate
Everyone remembers the blonde bombshell who lived to make Eric Forman’s life a living nightmare. Laurie Forman was the ultimate TV antagonist—manipulative, effortlessly cruel, and somehow always the "angel" in the eyes of her father, Red. But if you look closely at the middle of the series, the face of Laurie changes. Most fans know there was a switch, but the story behind the Laurie Forman actress transition is way more complicated than a simple contract dispute.
It’s actually a tale of two very different careers. One was a meteoric rise followed by a tragic, public downward spiral. The other was a professional "fixer" situation where an actress stepped into a role that arguably never truly fit her.
Lisa Robin Kelly: The Original, Indispensable Laurie
Lisa Robin Kelly didn't just play Laurie; she inhabited her. She had this specific, sharp comedic timing that made the "slut-shaming" jokes of the late 90s actually land as character beats rather than just cheap gags. She was 28 when she started playing the teenage Laurie in 1998, and her chemistry with the cast—especially the constant bickering with Topher Grace—was a massive part of why the first three seasons felt so electric.
She was promoted to a series regular in Season 2. Things were looking up. She was booking guest spots on big shows like Charmed and appearing in cult classics like Jawbreaker.
Then, she just... disappeared.

Midway through Season 3, Laurie was written out. The show said she went to beauty school. In reality, Lisa was battling demons that the public wouldn't fully understand for years. She later admitted in a 2012 interview with ABC News that a devastating personal loss—a miscarriage—sent her into a tailspin. She started abusing alcohol to cope. "I lost everything," she said candidly. "I was guilty of a drinking problem. And I ran."
The Failed 2003 Comeback
The producers actually tried to bring her back. She returned for a few episodes in Season 5, and fans were stoked. Laurie was back, marrying Fez to keep him in the country, setting up what should have been a massive Season 6 storyline.
But the "old" Lisa wasn't there. Her health was clearly failing, and her personal life was becoming tabloid fodder. She was fired for the final time in 2003. It wasn't because the writers ran out of ideas; it was because the set had become an impossible environment for someone struggling that deeply with addiction.
Christina Moore: The Season 6 "Replacement"
When Season 6 rolled around, the writers were in a corner. They had a "Laurie and Fez are married" plotline they had to resolve. Enter Christina Moore.

Moore was a MADtv alum and a total pro. She looked the part—blonde, beautiful, tall. But if you talk to any die-hard That '70s Show fan today, they’ll tell you it felt... off. It wasn't Moore's fault. She’s a great actress who went on to have a solid career in 90210 and True Blood.
But the "new" Laurie was softer. The edge was gone. The writers seemed to know it, too, because they barely used her. Moore only appeared in six episodes before the character was effectively vanished from the show forever. By the time the series finale rolled around, Laurie was just a name Kitty mentioned in passing.
The Tragic End for the Original Laurie Forman Actress
While Christina Moore continued to work steadily in Hollywood, Lisa Robin Kelly’s story took a much darker turn. Between 2010 and 2013, she was arrested multiple times for DUIs, spousal abuse, and assault. Every time a new mugshot surfaced, it broke the hearts of fans who remembered her as the vibrant star of Point Place.
In August 2013, she checked herself into Pax Rehab House in Altadena, California. She was 43 and, according to her agent, she was finally "hopeful and confident" about getting sober.

Days later, she died in her sleep.
The coroner eventually ruled it an "accidental unspecified oral multiple drug intoxication." It was a gut-punch to the cast and the fans. To this day, when people search for the Laurie Forman actress, they aren't just looking for a name—they're looking for an explanation of how such a bright comedic light burned out so fast.
Why the Recast Still Matters Today
In the era of reboots, like That '90s Show, Laurie’s absence is felt deeply. While the new series mentions that Red and Kitty had "two kids," Laurie hasn't made an appearance. This is likely out of respect for Lisa Robin Kelly’s legacy. Recasting her again would feel wrong, and using the Season 6 version wouldn't feel "canon" to the fans who grew up with the original.
Key Takeaways for Fans:
- Lisa Robin Kelly was the heart of the character but left due to a battle with alcoholism following a miscarriage.
- Christina Moore took over for only 6 episodes in Season 6 to wrap up the Fez marriage plot.
- The character was largely retired after 2004 because the "vibe" changed too much with the recast.
- Lisa Robin Kelly passed away in 2013, leaving a complicated but brilliant legacy behind.
If you’re revisiting the series on streaming, pay attention to the transition between Seasons 5 and 6. It’s a masterclass in how much an actor’s specific energy—that "it factor"—dictates the writing of a show. Without Lisa's specific brand of "mean," the character of Laurie simply ceased to function.
To honor the work of the original Laurie Forman actress, the best thing fans can do is appreciate those first three seasons where she absolutely owned the screen. If you or someone you know is struggling with similar issues to what Lisa faced, reaching out to organizations like SAMHSA (Substance Abuse and Mental Health Services Administration) is a vital first step toward a different ending.
