Super Trouper Meryl Streep Will Star in Mamma Mia!

She was hilarious as a washed-up Broadway diva in Death Becomes Her and was poignant singing country songs in Prairie Home Companion and Postcards from the Edge, but now Meryl Streep will sink her teeth into ABBA with the upcoming screen version of the hit stage musical Mamma Mia!

Streep stars as an ex-bohemian mom who comes face-to-face with three old boyfriends - one of whom now identifies as gay - when her daughter decides she wants to meet her real dad before she gets married.

The Devil Wears Prada star has a busy schedule, with Lions for Lambs (opposite Robert Redford and Tom Cruise) and Rendition (co-starring Jake Gyllenhaal and Reese Witherspoon) on the horizon.

No start date announced yet, but Streep has probably already memorized the lyrics to "Dancing Queen."
