Things got hot, as in RED HOT, at Hollywood Club MyHouse early Sunday morning when the DJ called out Chris Brown -- with Rihanna in the house!
RadarOnline.com learned exclusively from eyewitnesses that DJ Cobra sent a message that everyone in the club heard loud and clear.
It all took place during a celebration for Los Angeles Clipper Baron Davis' 30th birthday. Rihanna arrived around 12:30 a.m. Sunday. "She was seated upstairs next to Baron's party, dancing on the railing overlooking the club," a source tells RadarOnline.
That’s when Cobra took notice and instead of playing one of her many hit tracks, decided to send a different message. "He played a pre-recorded sound-byte over a beat that said, 'Chris Brown should get his ass kicked.' The crowd went wild," RadarOnline.com’s source says.
Cobra played and remixed the sentiment to Brown for almost a full minute, we're told.
Meanwhile, upstairs Davis celebrated his big 3-0 with Grey Goose bottle service and celeb pals including Jessica Alba and husband Cash Warren, as well as Scrubs' Zach Braff.
