Britney and the Boys Have a Sleepover

Britney Spears and her two sons had an overnight visit Saturday at her Los Angeles home.

It was the first time Sean Preston, 2 1/2, and Jayden James, 1 1/2 have been able to stay with mommy since she had a meltdown and was hospitalized in January.

The boos were dropped off Saturday and picked up at around 10 a.m. on Sunday.

A source explains, “Britney was very upset after the kids left.”

“She now does not know when she will get them next for an overnight. She complains it could be next week, or it could be three months.”

Meanwhile, baby daddy Kevin Federline was spotted partying in Miami over the weekend.

The Brit and K-fed will now face a custody trial in August after they were unable to hammer out an agreement last Thursday.
