In the Mix (2005)

Mobster Frank (Chazz Palminteri) hires hip DJ Darrell (Usher) to man the turntables at a party for his gorgeous daughter, Dolly (Emmanuelle Chriqui). At the event, some crooks pull guns on the gangster, and Darrell steps in to save his life. Frank then gives the DJ a job as his daughter's bodyguard, but, to the mobster's dismay, Dolly starts to fall for the smooth-talking Darrell. Their romance is interrupted when Frank gets involved in a mob war and drags Darrell along with him.
