Meet the totally fetch cast of the new Mean Girls musical

It's time to embrace those grool, all-carb diets because the Mean Girls musical is strutting its stuff at Cineworld this January.

Tina Fey's high school classic now gets an all-singing, all-dancing makeover, and the good news is Fey has overseen the change. In addition to creating the stage musical herself, Fey produces and directs the new film and appears as teacher Mrs Norbury.

How fetch is that? Angourie Rice (Spider-Man) plays Cady Heron and singer-songwriter Reneé Rapp plays Regina George, roles originally taken by Lindsay Lohan and Rachel McAdams.

Having torn up the Broadway stage, Jeff Richmond and Neil Benjamin's fabulously catty songs will now get a new lease of life at a Cineworld near you. To get you in the mood for an acerbic, day-glo big-screen sensation (we all need that in January), here's a behind the scenes look at the cast.
