The feud between Jay-Z and rapper Fat Joe may be simmering down, but it’s not over. Both attended a party at club Imperial the other night, and spies said they didn’t speak at all. One source says, “Jay-Z arrived and totally upstaged Fat Joe. He rolled up in a Jeep with no roof or doors, and was blasting out his new song. Then, when he got into the DJ booth, the whole club just came to a standstill. Fat Joe was not a happy camper. He made sure he wasn’t in the DJ booth when Jay-Z was there. Instead, he ordered a bottle of Hennessey and looked moody in the VIP area. Then, later on Twitter, he thanked Jay-Z for stopping by his party.”
