Beyonce and Kelly Rowland Join Fans at Karaoke Bar

The lucky fans at first do not realize that two ladies who enter their room when they are singing 2011's 'Party' are actually Beyonce and Kelly.

Beyonce Knowles and Kelly Rowland teamed up to surprise fans at a karaoke bar. The two singers surprisingly visited three lucky fans who were at Sing Sing Karaoke in Miami on Wednesday, January 8. At that time, Beyonce and Kelly heard the three women singing Beyonce's "Party" from another room.

"I was showing Beyonce how to work the remotes and she asked me where the music that was playing [in a separate room] was coming from," the karaoker bar's owner Kellie Pilicer told Us Weekly. "And I said 'Oh don't worry, it wont bother you.' And she said, 'No, I want to see who is singing my song.' "

The two singers went to the other room to find two women singing the tune. The fans invited them to sing and dance with them without realizing that they were stars. "Beyonce and Michelle started singing and dancing with them. They were also videotaping the whole thing. These girls had no idea it was them for the first couple of minutes. It was cute," Pilicer explained. Another woman in the room had passed out and the divas photobombed her before leaving.

Beyonce and Rowland were actually joined by Jay-Z, Michelle Williams, Timbaland and seven other people during the fun night. Beyonce wore all-black outfit and beanie, while Rowland sported a fury coat.
