Britney Spears plans on releasing her sixth album on December 2nd this year, her 27th birthday.

The aptly titled, ‘Circus’, follows up her 2007 album, ‘Blackout’, which was recorded when Britney’s mental stability was being questioned. For reasons I can’t seem to make out, that album cleaned up at the MTV Video Music Awards, winning three moonmen.

In other Britney news, it was Sean Preston’s 3rd birthday on Friday and Jayden’s 2nd birthday Sunday.  So Brit threw a party on Saturday and celebrated with close friends and family. The theme was all about cars and trucks with the cake being a big yellow truck.

The boys cruised around the party in their Ed Hardy battery operated vehicles, probably feeling cooler than ever.

Auntie Jamie Lynn and baby Maddie Briann attended, as well as Britney’s dad Jamie and mom Lynne. Celebrities who showed up with their kids were Gwen Stefani and son, Kingston, Jenny McCarthy and son, Evan. No sign of daddy, K-Fed, who was reportedly off partying in Vegas.
