LOS ANGELES (Reuters) - Pop star Britney Spears' 2-year-old son was taken to the hospital over the weekend after he had a reaction to something he ate, a statement on the singer's Web site said on Monday.

Jayden James was admitted to a Mississippi hospital during a visit by the singer and her two sons to her family home in Kentwood, Louisiana.

"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 (Tuesday)," said the statement from the Spears family posted on the official www.britneyspears.com Web site.

People magazine, quoting a source close to the family, said that Jayden had suffered "a terrible allergic reaction. He had hives, was itchy and irritable."

The source told the celebrity magazine that Jayden "is doing fine" and Spears, 26, and her mother, Lynne, spent Sunday night at the hospital with him.

Britain's Daily Mail newspaper had reported earlier that the toddler suffered an apparent seizure.

The trip by Spears to Louisiana, her childhood home, was the first time she had been allowed to leave California with sons Sean Preston, 3, and Jayden since their father Kevin Federline was given full custody in July.
