Rihanna’s boyfriend, Chris Brown, managed to lose his pants on stage while serenading a fan during his concert in Paris. I am not sure if Rihanna likes scene this but she should just take this one easy cause these pics just show how lucky Riri is with a guy like Chris. He is certainly hotness personified.

Watch a sweaty and shirtless Chris Brown, showing off his underwear on stage after the jump.
