SHAR TO BRITNEY: BUTCH UP!

Kevin Federline baby mama Shar Jackson seems to be having a schadenfreude festival at Britney Spears' expense, now that the pop tart's marriage to the former backup dancer seems to have hit a rough post-pregnancy patch.

The woman Federline left seven months pregnant with their second child, Kaleb, tells Us Weekly that Spears should have foreseen Federline's recent bout of partying all along: "C'mon, kiddo, did you think things were going to be different?" As for whether Federline was a good father, Jackson reveals to the mag: "Kevin was there for [first child] Kori every single day of her life until I told him to go out and get a job."
