{blackbabes} Brown performs lapdance for Hilson

R&B star Keri Hilson was left shocked and flustered after Chris Brown performed a raunchy lapdance for her onstage during a concert at the weekend - because he's like a "little brother" to her.

The Kiss Kiss hitmaker was performing in Providence, Rhode Island as part of radio station Hot 106's Holiday Hot Night event when he introduced Hilson at the show as his special guest.

She became the envy of all his female fans when a topless Brown instructed her to take a seat in the middle of the stage and began seducing her to the sounds of his track Sex.

Grinding up against her, he crooned, "You gon' get it tonight!"

Brown then continued to put on a show for Hilson as he belted out Take You Down, and the stunned singer admits she was a little overwhelmed by her pal's sexy surprise.

She tells WENN, "Chris is like my little brother, he's grown up over the last couple years into a man, learning from everything he's been through and that's what men do...

"It was so funny because we were joking around backstage before the show in Rhode Island, ...then he asked me if I'd be a guest on stage, so I didn't think it would be all of that!"
