Jamie Foxx’s appearance at the Belvedere Vodka (RED) Special Edition launch party in Hollywood Thursday night caused a little excitement – but not for the right reasons. According to TMZ.com, Foxx was involved in a fight at the celeb-studded bash, which featured a performance by Usher. As the R&B singer was performing, a man speaking with Foxx “suddenly pulled Jamie down and put him in a headlock,” TMZ said. Security reportedly pulled the unidentified partygoer away from the actor-musician and escorted him out. There were no injuries and the police were not involved.
