Jay-Z and Kanye West put aside their creative differences to celebrate the launch of their album, “Watch the Throne,” Monday night. West attended the early listening party at the Hayden Planetarium. Then, Beyoncé and her pal Kelly Rowland came out to support Jay at a later listening party for music-industry insiders. Following our story about disagreements over the Live Nation tour, Jay told Hot 97: “Kanye is my brother. Yes, we get on each other’s nerves, but that’s part of pushing each other.” He and West then went on to celebrate at The Darby until the early hours with Fabolous, Nas, Adrienne Bailon, Lindsay Ellingson, Jessica White and a gaggle of models who danced to “Throne” tracks mixed by DJ Jus Ske and DJ Mick Boogie. “There were a lot of girls all over Kanye,” our spy said, adding that West was “on his feet all night chatting up models.” He was last seen talking with stunning Romanian actress and Victoria’s Secret model Alina Puscau.
