Hollywood’s most stylish stars turned out this week to celebrate a great combination: Gucci and Rihanna. Guests like Sophia Bush, Nicky Hilton, Zach Braff, Camilla Belle and Rashida Jones mingled at the elegant rooftop lounge, ABH, atop the Thompson Beverly Hills Hotel and dined on luxe fare. And the party’s guest of honor couldn’t have been happier. “It’s really nice,” she told PEOPLE of being honored. “Gucci is here, and we support each other.” But the singer’s superstar supporters were just as honored to receive an invite. “I am a big Rihanna fan,” One Tree Hill star Sophia Bush told PEOPLE. “She’s really one in a million, and at the level she is, she is so sweet and genuine and kind,” while Jones gushed, “I’m excited to meet her! She’s really cool. So beautiful and so talented.” But hanging out with the singer wasn’t guests’ only reward. Long tables lined with Gucci shopping bags were filled with an extra-special surprise — all the ladies at the event were gifted with Gucci’s much-coveted Hysteria Clutch.
