Cher has joined Universal’s "Mamma Mia: Here We Go Again!". She hinted at her appearance in the movie over the weekend in a tweet and Variety has confirmed that she has been cast in the film.

Unfortunately, no details were given about the character Cher will be playing, but this this will mark her first live-action movie role in seven years, since 2010's Burlesque, where she starred alongside Christina Aguilera, Stanley Tucci, Kristen Bell and Alan Cumming.

Meryl Streep, Colin Firth, Amanda Seyfried, and Christine Baranski are returning, with Ol Parker writing and directing. The film goes back and forth in time to show how relationships forged in the past resonate in the present. Lily James will play the role of Young Donna. Young versions of Rosie and Tanya will be portrayed by Alexa Davies and Jessica Keenan Wynn, respectively. Young Sam will be played by Jeremy Irvine, while Young Bill is Josh Dylan and Young Harry is Hugh Skinner.
