It looks like a sequel to the hit musical "Mamma Mia", starring Meryl Streep, is on the way.  One of the movie's stars, Amanda Seyfriend, has confirmed there are plans in the works to make the movie happen, but nothing is certain as of yet.  She says: "I've been talking to some insiders and it's not something that they haven't been working on. I don't actually know anything other than that. I know it's still going to be Abba music, because what else would it be. Come on, I wouldn't do Mamma Mia 2 without Benny and Bjorn…I think we all had the best time and we all got along so well. It was like some days it felt like we were just people on vacation. I will do it. And I know Meryl's game as well, so bring it on. It will be so cool."
