Carly Rae Jepsen is set to play beauty-school dropout Frenchy in Fox's upcoming Grease: Live. The Call Me Maybe singer rounds out the Pink Ladies in the live TV musical, joining Vanessa Hudgens as Rizzo, Keke Palmer as Marty and You're the Worst's Kether Donohue as Jan.

Spare Parts' David Del Rio also joins the cast as Putzie, a member of the T-Birds with the previously announced Carlos PenaVega (Big Time Rush) as Kenickie. Bang Bang singer Jessie J will kick off the show with a performance of the classic Grease (Is The Word), first heard in the 1978 film starring John Travolta and Olivia Newton-John.

Julianne Hough and Aaron Tveit (Les Misérables) lead the adaption's ensemble as lovebirds Sandy and Danny. Grease: Live will air on Fox Jan. 31 (7 p.m. ET live/PT tape-delayed).
