Joe Jonas was rushed to the hospital this weekend for "severe stomach pain."

The 22-year-old was taken to the emergency room at Children's Hospital in Los Angeles on Sunday and released shortly thereafter.

It's not clear what was wrong, but rest assured Jonas is doing just fine...fine enough for sushi that night at Katsuya.

Jonas took to Twitter on Monday, "Hey everyone I'm fine I'm fine :-) thanks for the concern."

Could Joe's tummy troubles have stemmed from his late night partying in Chicago Friday night, as TMZ suggested?
