There's nothing quite like Memorial Day weekend in Las Vegas...
Chris Brown spent Sunday surrounded by bikini-clad women at the Palms Pool at the Palms Casino Resort with 9Group.
The "Fine China" singer soaked up the sun by the pool with an entourage of friends and possibly on-again girlfriend Karrueche Tran and later performed on stage in front of a massive crowd.
Brown kept cool in the desert heat in khaki shorts, a white shirt and a black baseball cap.
An eyewitness told E! News that Tran helped rub suntan lotion on Brown's chest and danced along while he gave his impromptu performance.
"They were definitely super touchy feely, looking into each others eyes while dancing," the insider added. "The two were side-by-side the entire time."
The two later stayed overnight in a hotel suite at the Palms.
It appears that Rihanna may be completely out of the picture. Brown's been spotted hanging out with his ex-girlfriend for the last month and even spent his birthday with her in Los Angeles.
