Celebrities came out in full force for the NBA All-Star weekend at the Staples Center in LA. Things kicked off on Friday night with Modern Family's Ty Burrell and Oscar performer Zachary Levi in the stands for the rookie challenge. Ty was back with his wife, Holly, to check out Saturday night's event, which also brought out Mark Wahlberg and his sons Michael and Brendan. John Legend and his girlfriend, Chrissy Teigen, were also on hand to watch the evening's performance by Cee-Lo Green, and they kept the fun going at an afterparty thrown by LeBron James and Jay-Z. There were even more famous faces in the crowd at Sunday's big game with Jay-Z and Beyoncé Knowles nabbing floor seats alongside Justin Bieber. Jay and B even shared some sweet PDA as the Western conference narrowly defeated the East. John apparently held things up when he spilled his drink on the court, though the show went on when birthday girl Rihanna, Drake, and Kanye West took center stage during halftime for a sexy medley. Kellan Lutz made an appearance during a break from filming Breaking Dawn, and Glee's Jenna Ushkowitz rocked her Lakers jersey to support the West Coast team. Check out tons of pictures from the weekend full of red carpets, dazzling basketball, and A-list cheering sections!
