WORKING ON A SIX-PACK Spears

Who dominated the Gossip Index this week? Radar tabulates ...

Britney Spears: While her 15-minute lip-synched comeback performance might not win any awards, Brit-Brit can take solace in knowing she's this week's queen of the gutter!

In addition to a potential tour, Britney is planning a makeover and interview with Allure. She's also allegedly writing a tell-all memoir trashing her mamma. Maybe she's just looking for a new parent altogether: Last week Rush & Molloy reported that Britters was thinking about hiring Jessica Simpson's dad, Joe, as her manager. This week, they're linking Brit to Usher's mom-ager, Jonetta Patton.

However it plays out, we hope everything comes up roses.
