The Kanye West and Kobe Bryant partnership might have taken a wrong turn somewhere.

The pair were photographed in the studio together last year when West was working on My Beautiful Dark Twisted Fantasy. The rapper, despite his Chicago roots, also said he wanted to be like the Los Angeles Laker.

Over the weekend, however, in a preview of a Nike commercial spot that will debut over the upcoming NBA All-Star Weekend, West (in character) is shown at odds with Bryant in a campaign for the baller's new sneaker.

"Bring him to me!" 'Ye screams in the clip, which was directed by Robert Rodriguez and also features Bruce Willis. "The Black Mamba ain't nothing. I'm the boss!"

The boss, apparently, wants Kobe's kicks: In the first clip that ran a week ago, a voiceover opens the spot by saying the NBA champion thought he was on a road trip to Dallas but found himself fighting for his footwear.

"Black Mamba, the boss wants your shoes," veteran actor Danny Trejo tells the high-flying basketball superstar.

Bryant is then shown slashing through defenders during a rooftop pickup basketball game and dunking buckets despite playing short-handed.

Two years ago, the duo were featured in another campaign for the NBA when West's "Amazing" was used for the playoff push alongside highlight clips of Bryant, LeBron James and the Celtics' Ray Allen.
