Britney Spears made an unexpected trip to the hospital over the weekend, but this time it wasn't the pop star's health that was the issue.
Instead, E! News has learned that Spears' youngest son, Jayden, was rushed to the emergency room by the pop star and sister Jamie Lynn on Sunday afternoon.
Britney herself drove the 2-year-old instead of waiting for an ambulance. While there's no official word on the reason for Jayden's admittance, reports are circulating that he suffered a seizure. The tyke spent Sunday night at the facility under observation.
Britney was spotted leaving Southwest Mississippi Regional Medical Center—the same hospital, coincidentally, where Jamie Lynn gave birth this year—earlier this morning but it was not clear whether Jayden had been discharged.
Britney's brother, Bryan, and her other son, Sean Preston, accompanied by a nanny, were also seen exiting the medical center today.
Britney, Jayden and Sean were expecting to spend a leisurely weekend with family in the pop star's hometown of Kentwood, La., the first time since her January meltdown that 26-year-old singer was allowed to take the boys out of California. The family only arrived on Friday.
A source close to the family told E! News that Kevin Federline has been made aware of his son's hospitalization and will fly out to the Mississippi facility should the boy not be discharged today.
