Bradley Cooper and Lady GaGa could be set to perform at Glastonbury.

TV presenter Edith Bowman has dropped a huge hint that the 'A Star is Born' co-stars may be one of the surprise acts at the music festival, after Bradley told her he has held talks with organiser Emily Eavis and her music manager husband Nick Dewey.

Speaking on TV show 'Sunday Brunch', she said: ''I may know one [surprise act], I can't possibly say.

''On my podcast I had Bradley Cooper talking about 'A Star is Born', and when I spoke to him I was like, 'I just want to see you guys do a gig, you know play it live.'

''He was like, 'Well we have been talking to Nick and Emily Eavis about it, we'd do the Park Stage,' and I said that would be amazing. Bradley Cooper and Gaga doing the Park Stage.''

Glastonbury gets underway on Wednesday (26.06.19) following a one-year break, and there are still two special slots yet to be filled.

At the time of writing, the Park Stage has a vacancy at 11.30am to 12.10pm on Saturday (29.06.19), and 6.15pm to 7.15pm on the same day.

In the 2018 movie, Bradley's alter-ego Jackson Maine performs on the famous Pyramid Stage at the Worthy Farm site in Somerset, south west England.

The movie also caused controversy when speculation emerged that Bradley and then-girlfriend Irina Shayk's relationship may have been on the rocks when he appeared alongside Gaga in the film.

A source said of the co-stars: ''They are both very hard-working, driven people and during the making of the film, had a very professional work relationship. From the moment they began collaborating with each other, people on the set saw how connected they were. There is endless chemistry between them.

''When they're together, they complete each other sentences. They are creatively so in tune with one another and seem to have a total intuition with one another.''

But Bradley and Irina insisted they were in a happy and ''secure'' relationship.

An insider said at the time: ''He is an honest guy and who is in a relationship and everyone has gotten very carried away with the gossip.

''Irina is with him a lot. She comes out all the time and they are really sweet together. Bradley is caring and conscious of her feelings. He doesn't want Irina to feel uncomfortable and she seems totally secure with their relationship.''

Earlier this month, it was reported he and Irina had split after four years together.
