Revellers at the Glastonbury Festival were stunned to find themselves partying alongside Hollywood hunk Bradley Cooper at the weekend.

The star of The Hangover movies and American Hustle had been attempting to keep a low profile at the massive event in Somerset, but his half-hearted "disguise" of stubble and shades didn't fool many people.

And now Instagram is plastered with selfies featuring delighted looking music fans standing next to the happy-looking star.

B-Coop was reportedly hanging out with actor pal Michael Fassbender at Worthy Farm, with Brad apparently wearing a backpack featuring a picture of the original cast of The A Team.

A witness told The Sun: "The boys were out to enjoy themselves big time.

"After midnight on Saturday, they made their way to Shangri La and then on to The Rabbit Hole. Revellers couldn't believe their eyes as they were dancing and stayed for a couple of hours.

"They kept moving when people realised who they were but it was pretty late. Most people were too drunk to care and didn't hassle them too much."
