Lady Gaga Plays Impromptu Show at Jazz Bar in NYC (Video)

Lady Gaga rocks a choker necklace and cap while walking to her car on Wednesday afternoon (July 27)) in New York City.

The night before, the 30-year-old entertainer reportedly hopped on stage at Rose Bar for an impromptu performance.

Gaga sang alongside jazz musician Brian Newman and The Dirty Pearls‘ lead singer Tommy London.

“She bantered a lot with the crowd,” a source told Page Six. “She was talking about the value of friendship and how much she enjoys playing music with her friends.”
