Jayden James Federline is Outta the Hospital

Britney Spears' two-year-old son Jayden is out of hospital and back with his family, according to a post on the singer's Web site.

"A source close to the Spears family has told us that Britney and family have left the Southwest Mississippi Regional Medical Center," says the update. "Jayden is fine."

The boy was hospitalized overnight after suffering a "terrible allergic reaction" to something he ingested.

Brit Brit needs to keep her cigarettes away from the young uns. So glad he's okay!
