Tina Fey talks working with Lindsay Lohan again in new "Mean Girls"

Twenty years after the original "Mean Girls" movie charmed audiences, its newest iteration, "Mean Girls: The Musical," has debuted at No. 1 at the weekend box office. This latest film, a blend of the original 2004 hit and the Broadway musical adaptation, marks a return for the franchise.

Tina Fey, the creative force behind the original screenplay and Broadway show, reprises her role as Ms. Norbury, the math teacher.

Another person returning to the movie was Lindsey Lohan, who was the star of the 2004 hit film. Fey said that Lohan, despite being seven months pregnant and residing in Dubai, was eager to be part of the new project. Her involvement was kept a secret, adding an element of surprise for the audience.
