Keri Hilson -- jokingly -- questioned Chris Brown's manhood in a backstage promotional video for her sophomore album 'No Boys Allowed,' which hits stores tomorrow, Dec. 21. "He says he's a man ...," Hilson jokes as a response to Brown's comments on being featured on her album despite its title. Hilson ends up eating her words when Brown seduces her onstage. Breezy got to work and gave the songstress a lapdance during his performance of his song 'Sex' at Hot 106's Holiday Night concert in Rhode Island this past weekend. Hilson remained in the hot seat while a topless Brown put on a show for her while performing his hit 'Take You Down.'

As mentioned in the first video clip, Brown and Hilson come together for the seductive track 'One Night Stand,' which is reportedly intended to be a sequel to Brown's 'Take You Down.'

Check out the video of Brown's lapdance after the jump.
