Lady GaGa's in the habit of shocking, and her visit to Birmingham on the Monster Ball tour was no exception.

The morning after her gig, she turned up to the Prince of Wales pub much to the regular customers' amazement.

According to The Sun, she spent two hours in the boozer, and drank whiskey and Diet Coke (we wonder if she asked for the cans to use in her hair?)

A source said: "She told locals how much she was enjoying having a drink on a day off because she can’t handle drinking before a show."

"She signed autographs for staff and left a huge tip – a few hundred pounds." 

She tweeted: "In a pub in England ruining bar napkins with lyrics and memories. Dreams are never weak like we are, drunk or sober." 

The Bad Romance singer also confessed this weekend that Beyonce is the "kindest" person in pop, and that she would eat a burger made out of human flesh if it meant two days of world peace, in a brilliant interview with ShowStudio.
