Chris Brown appeared on BET's 106 & Park on Monday, and while he spent plenty of time chatting with Bow Wow about his clothing line and his upcoming album, the most interesting bit from the interview is Chris talking about having sex on a plane!

"I'm not trying to be nasty. I was on a commercial flight in First Class," he said. "It was like one of them European First Classes where you've got the big front, so you can put the cover up so don't nobody see nothing."

Wonder who he joined the mile high club with? He wouldn't say, but he did speak about his ex-girlfriend Karrueche Tran for the first time since they broke up ... check out his interview above!
