Beyonce surprised fans who were singing one of her songs in a karaoke booth - when she turned up and joined them.
The singer and husband Jay Z, along with Timbaland and former Destiny's Child bandmates Kelly Rowland and Michelle Williams, visited Sing Sing, a karaoke bar in Miami, Us Weekly reported.
The bar's owner Kellie Pilicer said that when Beyonce joined the girls, they didn't initially recognise her.
"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," Kellie 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 mother-of-one walked down the hall to the girls' room, where they were singing her 2011 hit Party.
"Beyonce and Michelle started singing and dancing with them," Kellie told Us. "These girls had no idea it was them for the first couple of minutes."
Kelly and Beyonce, who is enjoying time off from her Mrs Carter World Tour, also photobombed one of the girls friends who was sleeping on the sofa, before leaving the room.
