Joe Jonas Rushed To The Emergency Room
A rep for Joe confirms he went to the emergency room at Children's Hospital L.A. on Sunday. We're told Joe was only at the hospital briefly ... and it's not clear what was wrong with him.
One potential hint -- on Friday night (into Saturday morning) Joe was out at a Chicago hot spot Board Room Nightclub partying after his concert.
Whatever the problem was ... Joe felt good enough to eat out Sunday night -- we spotted him and his bro Nick leaving Katsuya Sunday night. Sushi after stomach troubles? Risky, Joe. more on this story
