34571323 Britney Spears' son Jayden James ate something bad Jayden James is going to be OK!

Apparently, it was something that Britney Spears’ son Jayden ate Sunday afternoon that turned him all itchy, with icky hives and acting all fussy and irritable.

Jayden was rushed to a Kentwood-area hospital at 1:30 p.m. Sunday. But sources say the toddler is not in danger.

"He’s doing fine," the source tells People. "They kept him overnight."

Britney and her mother, Lynne Spears, spent the night at the hospital with Jayden.

As for what caused the reaction, "They’re just not sure," said the source. But you can bet their dad Kevin Federline will want a full accounting of the menu on Sunday.

Today, Spears’ team posted this statement on her website: "Jayden James Federline was admitted to the Southwest Mississippi Regional Medical Center on Sunday, November 9th. Doctors concluded he had a reaction to something he ingested. He is expected to be discharged tomorrow."

Ingested is fancy speak for something he ate.
