"Toxic" trainwreck Britney Spears' crazy really has hit the fan. TMZ has learned that the pop tartlet recently called up "OK!" magazine's main number and asked for "OK!" Editor-in-Chief Sarah Ivens. Miraculously, the mag's receptionist believed it really was Brit-Brit, and she was patched through to Ivens.
It seems Brit wanted to talk biz and negotiate a tell-all interview with the magazine, and not surprisingly, Ivens agreed. Miss Brit-Brit is expected to dish on her beloved babies; her mama drama, the Fed-Ex, and more. The Britabulous issue is expected to hit stands next week, y'all.
