Britney Spears Enters Rehab -- Third Time

Who else is so over this?

Britney Spears reentered treatment facility, Promises, in Malibu, Calif. Her mother, Lynne Spears drove her back last night!

Yesterday evening, Britney showed up at the door of whose house? None other than ex-hubby-to-be Kevin Federline. And he, uh, wouldn’t let her inside. Video footage of a furious Britney flailing her arms and attacking paparazzi is supposed to surface later today…

Meanwhile in baby news, K-Fed is pressing the courts to speed up the custody dispute over his and Britney‘s two sons — Sean Preston, 17 months, and Jayden James, 5 months.

Which parent is most fit in this lose-lose situation? Britney or K-Fed?
