Diddy underwent quad surgery with only 24-hour notice and had to cancel a scheduled appearance on Friday. The rapper told fans he was going under the knife to repair a quadriceps tendon tear in a series of videos shot from his hospital bed. In the videos, shared on his IG, Diddy was seen getting prepped for surgery. He was seen lying in the bed wearing a hospital gown and cap while nurses got the star ready ahead of his operation. The 50-year-old revealed he didn't have much time to prepare for the surgery and had to cancel his San Fransisco appearance just hours before he was missing the event.
