Chris Brown stoked the fires of his beef with rapper Drake at a Hollywood music venue on Wednesday, as he performed a six-song impromptu set after hearing a snippet of his rival's new single.
Brown rolled into The Emerson Theater with a group of friends, after hitting a charity function in at Studio City, California, bowling alley Pinz, and the singer was inspired to do a lot more than party.
When the house DJ cued up Drake's new single "Started From The Bottom," an omg! source says Brown immediately requested a microphone.
"The DJ can play this s***, but I want you all to know…F*** Drake!" Brown said, addressing the club with his middle finger raised.
The crowd was divided: Some revelers on the dance floor joined him in flipping the finger, while others barked out asking him to drop the microphone and let the night resume.
That wasn't happening. Brown immediately burst into song, running through his hits like "Turn Up The Music" and "Beautiful People."
We can't knock him. Dominating the soundtrack is a creative and peaceful solution to dissing a fellow entertainer. Just ask Reggie Bush – the NFL player and Kim Kardashian's former boyfriend was in the house, and eventually jumped up beside Brown and acted as his hype man.
Brown and Drake have had issues since a nightclub altercation in June of 2012, allegedly over Brown's girlfriend Rihanna.
After his spontaneous performance, the 23-year-old, rocking a Miami Hurricanes hoodie, sipped Ace of Spades rosé and plenty of vodka.
And it wasn't all beef all night. Brown sent more than $10,000 worth of champagne (approximately six bottles) to former Dallas Cowboy and football legend Michael Irvin, who was celebrating his birthday.
Brown bounced around 2 a.m. through the rear patio, passing actor Chris Pine, who enjoyed his evening with friends and a few cocktails.
There wasn't much rest for Brown, as Thursday morning he headed to Bermuda, a bit tired, we can imagine.
He and his bodyguard got into a reported argument on a stop to refuel. We don't know specifics, but we for sure know he had a long night.
