The Prince Of Wales regulars were eventually won over when she decided to pick up the tab for everyone in the bar, as well as leaving a hefty tip, about "a few hundred pounds."
Dressed in black leather and shades, Gagaloo drank whiskey and Diet Cokes while penning lyrics and tweeting.
While sitting at the bar, she tweeted:
In a pub in England ruining bar napkins with lyrics and memories. Dreams are never weak like we are, drunk or sober.
One of the patrons said:
"Everyone was stunned when this striking blonde came in. Most of the blokes had no idea who she was at first. She sat at the bar with a pal for two hours, downing spirits and scribbling notes. She told the 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."
Way to make your UK fans happy, GaGa!
