Wiz Khalifa lived the high life while partying in Las Vegas for his 24th birthday. The “Black and Yellow” MC boarded a private plane with his girlfriend Amber Rose and friends and headed to the Playboy suite at the Palms hotel. He did his happy dance as his stylist presented him with some fly birthday gear. And it wouldn’t be Wiz’s day without a fresh delivery of weed and a cake in the shape of a marijuana leaf. “It’s a reefer party,” he announced.
