In a new interview with Entertainment Tonight, the 44-year-old actress — who was promoting her new film Are You There God? It's Me, Margaret — said she would "never" say no to Tina Fey, if the latter asked her to come onboard for the upcoming Mean Girls musical movie. "She's the greatest," McAdams raved of Fey, 52, who costarred alongside McAdams in the original movie and wrote the screenplay for that film. Fey also wrote the Broadway musical on which the new film is based. She is also co-producing the musical film. Although the original Regina George actress isn't "in the works" currently to make an appearance, "We'll see how it all shakes out," McAdams added.

RELATED VIDEO: Rachel McAdams Would Love to See the Mean Girls Musical McAdams starred as the queen bee in the 2004 hit teen comedy written by Fey and directed by Mark Waters, inspired in part by Rosalind Wiseman's 2002 book Queen Bees and Wannabes. She was joined by Amanda Seyfried and Lacey Chabert as the Plastics, the group of popular girls in school who are eventually infiltrated and taken down by Lindsay Lohan's new kid Cady Heron — but not before she loses herself in the fast life of high-school politics. During an April 2020 appearance on the Heroes of Health: COVID-19 livestream, McAdams briefly found time to consider a return as Regina — one of her most iconic roles. "It would be fun to play Regina George later in her life and see where life took her!" the actress replied when asked about a potential sequel to Mean Girls, according to Yahoo Entertainment.
