Nick Jonas definitely had a super sweet 16 birthday party. He and his brothers got to play a private baseball game with their friends at LA's Dodger Stadium. "[Kevin, Joe and Nick] rented out the stadium last night to play a baseball game with some friends," an insider tells E! News. And money was clearly no expense, as the boys shelled out upward of $30,000 for the less than three-hour game. Renting the field starts at $25,000, lights are $5,000, and food, drinks and music run around $1,000. But hey, you only turn 16 once, right?
