Britney Spears' Hiatus Is History

Pop singer has been at work in the studio.

UNIVERSAL CITY, California — Britney Spears' hiatus is history.

"I've been in the studio for a while," Spears revealed at the Neil Bogart Memorial Fund's annual Bogart Tour for a Cure event on Monday. "I've written plenty of stuff. It's really cool, really good."

Spears said she took three months off after her world tour wrapped in July — she had originally vowed to take six — but has since been working on the follow-up to last year's Britney.

While British tabloids following Spears on a recent London trip linked her with producers William Orbit (Madonna), Guy Chambers (Kylie Minogue) and Shep Soloman (Westlife), the singer would not confirm any of her collaborators.

"I can't tell you, then it won't be cool when it comes out," Spears said. "There has been a couple [producers] overseas."

Spears was honored Monday with the Children's Choice Award for her charitable efforts, which include a namesake foundation and a performing arts camp to benefit sick and disadvantaged children. Britney also raised $1 million during her Dream Within a Dream Tour for kids affected by the September 11 attacks.

"I'm very excited about tonight," Spears said. "Any time you can go to an event where it's about giving back, that's what it's about."

Britney's next record likely won't be released until late next year, though fans can keep up with the pop princess through "Stages," a book and DVD due out later this month (see "Britney Spears Thanking Fans With Tour Book, DVD").
