Although Johnny Depp was probably the most talked-about actor at Glastonbury this year, primarily because he talked about assassinating Donald Trump, he wasn't the only one there.
As it turns out, Bradley Cooper was also at Glasto and even took to the stage during Kris Kristofferson's set with an electric guitar. Whether he actually played the guitar or if he was just miming over a track, nobody's really sure, but it is known that the short interlude was for the upcoming remake of A Star Is Born.
Funnily enough, Kris Kristofferson played the same role that Cooper's playing back in 1976 - which is probably why Cooper was there. As well as this, the scene in which Cooper's performance was actually filmed by a familiar face - namely Lars Ulrich, Metallica's drummer.
Lady Gaga and Bradley Cooper have been filming A Star Is Born for a number of months, and turned up at Coachella back in April to capture a few scenes in front of live audiences. The film, which is directed by Cooper, will be the fourth version of the film. The original was made back in 1937 with Janet Gaynor and Freddie March, was remade first in 1954 with Judy Garland and James Mason, in 1976 with Kris Kristofferson and Barbara Streisand, and the latest version will be released on September 8th, 2018.
