Britney Spears says 'I made a mistake'

Sadly, she's not referring to anyone named Kevin.

Other than Federline's extended family -- or perhaps Christina Aguilera and the panelists of "Best Week Ever" -- is anyone rooting for this marriage to work out?

As long as they're together, there's no hope for a relevant, hot Britney to return to the spotlight. World peace depends on their breakup.

Britney: Sometimes I run. Sometimes I hide. Sometimes I'm scared of you.
