The iconic Hollywood costars — who also worked together on 1983’s Silkwood and 2003’s Stuck on You — were in London promoting Mamma Mia 2 when they pulled the cheeky move on the blue carpet. The musical — inspired by the ‘70s Swedish pop group ABBA — also stars Amanda Seyfried, Lily James, Pierce Brosnan, Dominic Cooper and Christine Baranksi.
Teasing the moment, Cher later took to Twitter to write, “Well it was a GREAT NITE…I ❤ EVERYONE IN THE FILM,& EVERYONE WHO WORKED ON THE FILM…..ESPECIALLY MARY LOUISE STREEP.”
Singing ABBA’s “Fernando” in the movie must have struck a chord with Cher. In an interview with Kathie Lee Gifford, the “If I Could Turn Back Time” singer — who was once in an ABBA music video — revealed she has plans to release an entire album of ABBA covers!
Mamma Mia 2 will hit theaters on Friday, July 20.
