WATCH: Lady Gaga Surpises Nightclub Patrons with Jazzy Performance...(Video)

Patrons of the Plaza Hotel's Oak Room Nightclub got a real treat last night when Lady Gaga showed up to perform jazz tunes with scheduled entertainer, singer/trumpeter Brian Newman. Pic #2 is a doozy, isn't it? Prior to the gig, she tweeted to her fans: "Looking forward to the gig at the @oakroomny @theplazahotel tonight! First show of 2011!!" No doubt, this was a real coo for the establishment. Staffers also too to Twitter in an excited attempt to draw in more patrons: "Come to the packed @oakroomny @theplazahotel right now to see LADY GAGA — singing, dancing — its amazing!!! Lady Gaga @oakroomny right now singing LIVE!!!!!... its packeddd." How cool is THAT? Don't trip. You can join in on the fun too. Check it out, below:
