Los Angeles - Rachel McAdams would sing in a musical version of Mean Girls.
The blonde actress - famous for her role as bullying popular girl Regina George in the 2004 film, which also starred troubled Lindsay Lohan - says "everybody" could get involved, although she doesn't think her character can actually sing.
The Morning Glory star, 32, exclusively told BANG Showbiz: "Sure. Yeah, why not? But I don't think my character - if I played Regina again - something tells me that she probably wasn't a good singer. "
When asked whether Miley Cyrus would be a suitable choice to star in a musical production of the comedy she said: "Yeah sure, everybody, let's get everybody involved!"
Speaking at the UK premiere of Morning Glory at the Empire cinema in London's Leicester Square, she added that she was a lot younger when she played Regina so she hoped she had come a long way since then.
She told BANG Showbiz: "It was a long time ago so I hope so."
In Morning Glory Rachel worked alongside acting heavyweights Diane Keaton and Harrison Ford - and revealed she would also like to work with Joan Cusack.
She said: "There's so many people I would love to work with. I love Joan Cusack actually. She's one of my favourites."
