Is Selena mad that Justin & Nick hung out?

The blogs were abuzz when news broke that Nick Jonas and Justin Bieber recently spent an afternoon chilling out. Here's how it went down: First, the guys tweeted about their bro bonding, with Nick saying 'Just played @justinbieber in ping pong. Went to deuce both times, but he's the ping pong champion. #Igotyounexttime." Since Nick is Selena's ex and Justin is supposedly on his best behavior with Sel, gossipers whispered that Selena was majorly miffed. "Hanging out with Nick proved that Just wants to be a jerk, and Selena's sick of being heartbroken," Selena was A-OK with the guys gab sesh. A source close to her confirms, "Selena and Justin didn't not get in a fight over him hanging out with Nick Jonas," adding that Gomez "never gave it a second thought." Whew!
