Jay-Z and Kanye West have celebrated the launch of their album 'Watch the Throne'.

The pair - who joined forces to create the record, which is set to be released on August 8 - were partying to their own tracks mixed by DJ Jus Ske and DJ Mick Boogie at The Darby restaurant in New York City alongside Fabolous, Nas, Adrienne Bailon, Lindsay Ellingson and Jessica White.

An onlooker told the New York Post: "There were a lot of girls all over Kanye," adding he was "on his feet all night chatting up models".

Beyonce and Kelly Rowland came out to support Jay at a listening party, after Kanye had been to an early event at the Hayden Planetarium.

The '99 Problems' rapper - who does not always see eye to eye with Kanye - admitted the pair do have creative differences, but he isn't fazed by it.

Jay told Hot 97: "Kanye is my brother. Yes, we get on each other's nerves, but that's part of pushing each other."
