Britney Spears' Son 'Doing Fine' After Hospitalization: Report

Jayden James, 2, was hospitalized for an allergic reaction.

Britney Spears' youngest son, Jayden James, appears to be fine after an overnight hospitalization for an allergic reaction, an unnamed source told People magazine.

Spears had taken her sons, Sean Preston and Jayden James, back home to Kentwood, Louisiana, for a visit — the first since her custody battle with ex-husband Kevin Federline — when 2-year-old Jayden reportedly broke out into hives.

The family took him to Southwest Mississippi Regional Medical Center in McComb, approximately 20 miles away from Kentwood, for emergency care Sunday. Being a small town, Kentwood has few options for medical care, including an outpatient clinic, a nursing home and a hospital, Hood Memorial, within 15 miles of city limits. After Hood Memorial, Southwest Mississippi Regional is the closest facility.

Britney's brother, Bryan, was videotaped outside the Southwest Mississippi Regional emergency entrance, bringing in fast food on a few occasions and taking care of 3-year-old Sean on another. Southwest Mississippi Regional Medical Center told MTV News that it's hospital policy not to confirm admissions or disclose patient information.

"[Jayden] is doing fine," the source told People. "He had hives, was itchy and irritable. ... They're not sure [what caused the reaction]. ... They kept him overnight."

Spears' rep's office had no information on the situation at press time.

A rep for Federline told MTV News she had no comment whether the father would be traveling to see his son in the hospital.
