Just in time for the holidays: Britney Spears.

The singer’s new album, Circus, will drop on December 2 — her 27th birthday — her music label Jive/Zomba announced Monday.

The first single, “Womanizer,” will hit radio September 22.

Spears — who won big at last weekend’s 2008 MTV Video Music Awards (including Video of the Year) — has been in the studio all summer.

“She’s working with a team of top-notch producers and songwriters and we’re very excited about what she’s accomplished so far,” her manager Larry Rudolph said in July.

Spears took a break from work this past weekend to celebrate her boys’ birthdays.

Along with her family — including sister Jamie Lynn and her daughter Maddie, brother Bryan, mom Lynne and dad Jamie — she threw her sons a car-themed joint bash in Beverly Hills on Saturday.

Sean Preston, who turns 3 on Sunday, and Jayden James, who turned 2 on Friday, were given miniature SUVs with personalized license plates.

“Britney was looking on like a very proud mommy,” a source tells Usmagazine.com. “She got a kick out of watching the boys in their cars and was laughing and smiling.”
