Diddy drops in on sweet 16

P Diddy mistakenly crashed a $100,000 sweet 16 party in Central Park Monday — thinking it was a wild rave for grown-ups. We’re told the music mogul was near the Victorian Gardens amusement park, which had been rented out for real-estate investor Ronald Edelstein’s daughter Joelle’s bash, when he heard the tunes from DJ Domingo blaring and saw flashing lights over a built-in dance floor, so Diddy decided to go in and check it out. “I don’t know how he got in, but maybe security recognized him,” says a witness. “He had four or five bodyguards. He just came and took a look, but didn’t stay long. He never talked to the birthday girl.” We’re told Diddy only stayed a mere 15 minutes and that his people said no when asked for photos. Perhaps he felt out of place at the Coachella-themed party for teens, which included booths like a hair-braiding bar and a choker-making station? Diddy and girlfriend Cassie were spotted having cocktails at nearby restaurant the Wayfarer the same night. The event was planned by Everything Samantha, which is owned by Edelstein’s other daughter.
