A new celebrity trend! Pregnant behind bars!
A Manhattan judge threw Foxy Brown behind bars on a probation violation charge -- a stunning blow to a rascally rapper who's uncanny ability to remain free despite numerous scuffles with the law had made her appear jail-proof.
Foxy -- who is three months pregnant, according to her lawyer -- will spend at least two weeks, until Sept. 7, in Rikers, which has a pre-natal unit for pregnant inmates.
The rapper announced in court that she also has plans to get married -- she so wants to be Nicole Richie.
