Dr. Dre Working On Score For 'Bad Boys II'

Action comedy starring Will Smith, Martin Lawrence due in theaters July 18.

Dr. Dre is a bad boy too.

He's not in "Bad Boys II" (rather, he has a cameo in the competing "Hollywood Homicide"), and he doesn't have a song on Bad Boy Records soundtrack, but he's involved in the film and its music. For the first time in his distinguished career, Dre is working on the score of a movie.

The producer behind some of Eminem and 50 Cent's biggest hits is in his studio now, working on music for the Will Smith/ Martin Lawrence action comedy, according to his spokesperson. A spokesperson for the film said Dre is making beats to aid composer Trevor Rabin ("Bad Company," "Armageddon"). It is not known whether the score will be released as an album.

Featuring Nelly, Lenny Kravitz, Beyoncé Knowles and others, the soundtrack is due July 15, three days before the movie hits theaters (see "50 Cent, Biggie, Justin Timberlake On 'Bad Boys 2' Soundtrack").

Dre took a break from producing Ice Cube and Eve to score the movie (see "Eve Says Dr. Dre Will Be 'All Over' Her Next Album"). He's also working on his third album, which he claims will be his last (see "Ice Cube Puts Chill On Dr. Dre's Supposed Final Album").

"Bad Boys II" is said to be action-packed, but it also finds Smith smitten with his partner's sister, played by Gabrielle Union (see " 'Bad Boys 2' Co-Star Gabrielle Union Says Flick Will Be 'Crazy Action' ").
