Charlie Sheen heals quickly.
Hours after being rushed to L.A.'s Cedars-Sinai Medical Center Thursday morning -- following nearly two straight days of partying -- the Two and a Half Men star, 45, has checked out.
"Charlie Sheen left the hospital last night and is at home," the star's rep tells UsMagazine.com.
Although the actor's father Martin Sheen and ex wife Denise Richards were both spotted at Cedars-Sinai -- "Denise looked like she'd been crying," an onlooker told Us -- a pal told Extra that the actor had only suffered a hernia injury.
And while doctors say Sheen may need surgery to repair the hernia, his rep reports that he'll be back to work next week, when his CBS hit returns from hiatus.
His rep tells Us, "He will be on the set of Two and Half Men on Tuesday."
