It's finally here! The first official trailer or Mamma Mia: Here We Go Again has just arrived!
Lily James, Keenan Wynn and Alexa Davies join the cast as young trio - Donna and the Dynamos.
Don't worry, Meryl and her girls are back for the sequel, too! So are their long lost flames Pierce Brosnan, Colin Firth and Stellan Skarsgard.
Amanda Seyfried is coming back too, as Donna's daughter Sophie. And, there's a baby on the way!
