But it appears she's not done with the movie world yet; the superstar just confirmed she is somehow involved with the Mamma Mia! movie sequel, Mamma Mia 2: Here We Go Again.It all started with Twitter user and presumed Cher fan @itzaneylis asked, "excuse me you wonderful human, could you pls tell us something about this before I get too excited????" with a link to an article about Cher "lending her vocal talents" to the film:She confirmed, tweeting, 'WELL…IM IN MOMMA MIA2 🎂':It's still unclear what the exact nature of the film sequel will be, but it'll reportedly be a prequel with British actress Lily James playing the younger version of Meryl Streep's Donna. With most of the first film's cast returning, Mamma Mia fans everywhere should also lay their love on Cher.
