Britney Spears' family reunion took a dramatic twist yesterday after son Jayden James was rushed to hospital after a suspected seizure.

The two-year-old was said to be enjoying play time with the Spears family in Kentwood, Louisiana when the attack took place.

Jayden reportedly became incoherent and unaware of his surroundings, prompting Britney to seek immediate medical attention.

A source tells the Daily Mail, “One minute Britney and her sons were relaxing and enjoying their first visit to Kentwood in months, and the next minute Jayden had fallen ill.

“He was vague and unresponsive so Britney dialled an ambulance.

"But she was told it would take half an hour to arrive, and she was best trying to get Jayden to the hospital herself.”

Britney's son reportedly stayed in overnight for observation at the Southwest Mississippi Regional Medical Centre.

Jayden's father Kevin Federline is said to be flying out from L.A. to be with his son.
