Lindsay Lohan's reunion with "Mean Girls" cast has all but confirmed by co-creator Tina Fey but it's not what fans are hoping for as the "30 Rock" actress is hoping to reunite LiLo with Rachel McAdams and Amanda Seyfried in a musical.

During the Hollywood premiere of "Muppets Most Wanted," Tina Fey acknowledged that it's the 10^th anniversary of the movie.

"We're working on the musical, that's going to be in a couple years, I guess. So hopefully there will be like a screening or a party, but that's it. But that would be good, right?" she said, dashing any hopes that Lindsay Lohan's "Mean Girls" 2 reunion would happen.

"I hope everyone can come," she said. "I hope we can organize something.

Released in 2004, "Mean Girls" was based on Rosalind Wiseman's book "Queen Bees and Wannabes." The screenplay was written by Tina Fey and it starred Lindsay Lohan, Rachel McAdams, Amanda Seyfried and Lacey Chabert.

The film was also a surprising hit for its time, considering that it was made on a shoestring budget of $17 million, quite low for a Hollywood movie, and grossed $86 million in the US alone. It also launched the careers of LiLo, Rachel McAdams ("The Notebook") and Amanda Seyfried ("Les Miserables.")

Lindsay Lohan was all in for a reunion with the other "Mean Girls" cast, TMZ reported.

Appearing on Jimmy Fallon's show on Thursday night, Lindsay Lohan embarrassingly confessed that she was one of the last persons to know about the reunion and only after into Tina Fey recently.

"This is important. This needs to happen," Lindsay Lohan said, while promoting her own self-titled series on OWN.

Jimmy Fallon even suggested to host the reunion on "The Tonight Show."

Citing sources, TMZ claimed that Amy Poehler, Rajiv Surendra, Jonathan Bennett, and Daniel Franzese have already committed to join the cast should there ever be a "Mean Girls" reunion.
