A track believed to be from the forthcoming Kanye West and Jay-Z joint album 'Watch the Throne' has leaked. Titled 'That's My Bitch' the track name checks the forthcoming effort in West's first verse. "I paid for them titties/Get your own/It ain't safe in the city/Watch the throne," Yeezy raps.

La Roux's Elly Jackson, who hit the studio with West earlier this year for a number collaboration, including vocals for his 'My Beautiful Dark Twisted Fantasy' track 'All the Lights,' contributes to the refrain on the track. Although it hasn't been confirmed, it sounds like West's 'Lost in the World' collaborator, Justin Vernon of Bon Iver fame, does some wailing in the background as well. The upbeat track sports some tribal drums and even has Jay-Z giving a shout-out to his main squeeze Beyonce. Awe.

Check the track out after the jump.
