Britney Spears britjayden460.jpgBritney's son Jayden James was rushed to the hospital last night, Entertainment Tonight has confirmed.

Britney's youngest son reportedly lapsed into a "vague and unresponsive" state on Sunday afternoon while the family vacationed in Kentwood, Louisiana.

“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," a source told The Sun.

Doctors were unable to pinpoint the problem immediately and kept the toddler in for overnight observation. Britney is reportedly so distraught, she's asked for a bed next to Jayden's so that she can stay with him at all times. They are at Southwest Mississippi Medical Center, where Jamie Lynn gave birth to her daughter almost three months ago.

Jayden's dad, Kevin Federline is reportedly heading to Louisiana to be with the family.

A spokeswoman for the hospital told X17online, "The hospital does not release information about patients and I cannot confirm or deny whether Ms. Spears' son is a patient here."
