Joe Jonas was rushed to the hospital yesterday due to severe stomach pains, TMZ is reporting. A rep for the singer confirms that he was taken to the emergency room at Children’s Hospital in Los Angeles.

Though the exact nature of Joe’s ailment has not been revealed, it apparently wasn’t a major illness. He was only at the hospital briefly, and the gossip site spotted him later in the evening having dinner with brother Nick and some friends at upscale sushi joint Katsuya. He even joked with the paparazzi about creating a new Jonas Brothers brand of cereal.

Jonas appeared Friday at Chicago’s Allstate Arena as part of the B96 Jingle Bash, where he was joined by Enrique Iglesias, LMFAO and Jason Derulo. TMZ noted that after the show, he partied into the next morning at the Board Room Nightclub.

The 22-year-old ‘Just in Love’ singer has not yet tweeted or otherwise personally addressed the incident. Hopefully it wasn’t anything too serious!
