According to People, Bret Michaels underwent emergency appendectomy surgery early Monday morning. The former Poison frontman and star of VH1’s Rock of Love was rushed to the hospital at 1 a.m.; his rep says he “remains in the hospital, is doing well and beginning the recovery process.” Some of the rocker’s April tour dates will be rescheduled.

UPDATE: A rep for Michaels confirmed to People that the rocker will remain under hospital supervision following his emergency surgery. The rep says Michaels saw his temperature spike overnight, which could be an indication of an infection.
