Justin Bieber and Tyga had the club going up on a Sunday when they decided to give an unexpected performance.
The 21-year-old pop star and 26-year-old rapper hit the stage at 1OAK in Los Angeles, Calfornia and did renditions of Bieber's hits, "What Do You Mean?" and "Sorry." An eyewitness said Justin started performing around 1:45 a.m., then, after 10 minutes, Tyga joined him on stage. Justin asked if the crowd was having a good time -- and advised them to "get out" if they weren't. "There were no boos at all," the eyewitness said. "It was a great, positive vibe."

The women at the club might also have received a special gift from Bieber. On Sunday, he posted a pic of red roses, writing: "We got flowerz for the ladies."
While we've yet to see Bieber and Tyga double date, we did spot Kylie Jenner with the rapper at 1OAK days prior to Sunday's impromptu performance. Check out the 18-year-old reality star's sexy leather jumpsuit.
