Britney Spears' life has become nothing short of a constant roller coaster ride.  She's been in and out of rehab, and she came damn close to loosing everything including her kids!  We haven't heard much from Britney's family 'til now... and it ain't good!

Britney's estranged father, Jamie Spears, on Friday when he fired off an email to the New York Post calling Britney out on her bad behavior.

Not only does Mr. Spears disapprove of what Britney is doing, but he also sides with her manager over the recent firing.  Britney fired her manager, Larry Rudolph earlier in the week.

"I am praying for my father. We have never had a good relationship," Britney told the Post through her rep. "It's sad that all the men that have been in my life do not know how to accept a real woman's love. I am concentrating on my work and my life right now."

Do all successful females have a wacky, estranged father?!
