See Lady Gaga Sings Sinatra During Surprise at Hollywood Bar

The crowd at the Black Rabbit Rose bar got an extra special Gaga treat. 

Lady Gaga surprised the crowd at the small Hollywood venue crooning some of Frank Sinatra’s iconic songs. 

“I’m here to ruin the party. I’m so sorry,” Gaga said to the audience, and then continued belting out Sinatra’s “Call Me Irresponsible” and “Fly Me To The Moon.” The two songs are featured regularly as part of the singer’s Las Vegas residency performances. 

“My whole life, you know, I’ve been called irresponsible,” she added. “It doesn’t make me so mad because it’s kind of true… and I like to hear the truth.”

The Oscar winner looked absolutely gorgeous clad in a black leather dress and a matching fur coat for her first gig since that duet with Bradley Cooper at the Academy Awards.
