Today on Twitter, Nick Jonas said a lot without saying anything at all. The 18-year-old Jonas Brother tweeted that he's got big news that he can't wait to share, which has some folks speculating that he might be getting married, while others believe he could reveal that he's got a big stint on Broadway coming up. While the baby Jonas was teasing his followers, the trio tweeted from their joint account, wishing their fans a happy Labor Day. Sean Kingston, who was just fitted for a grill with Justin Bieber, also enjoyed some holiday festivities, as did Keri Hilson, Game, Diddy and more.
