Lady Gaga leather glasses singer hotel psychedelic kaleidoscope Black Sheep Syndication

Is she headed to the chocolate factory?!

Lady Gaga left her hotel in London yesterday, and the singer opted to wear a leather pants suit and crazy kaleidoscope glasses to hit the town.

Mother Monster is across the pond to perform her new single "Swine" on Monday at London's Roundhouse as part of the month-long concert series.

The chart topper released a clip of herself rehearsing for the show, and we think she has another #1 hit on her hands!

The video shows the Grammy winner banging on the drums and keyboards as she sings the lyrics, "I know, I know, I know you want me/You're just a pig inside a human body."

After donning that skimpy outfit at the VMA's, we're sure a lot of people want her!
