The 'See No More' singer apparently was suffering from severe stomach pains when he checked into the emergency room at Children's Hospital.
A rep for Joe confirmed to TMZ that doctors did briefly examine the star's abdomen, but he was quickly released from the hospital and allowed to return home.
Joe was seen later on Sunday having dinner with brother Nick Jonas at LA eatery Katsuya.
The star recently returned home to LA after supporting Britney Spears on her 'Femme Fatale' tour.
Joe released his first solo album FastLife in October.
