Christina Milian and Sarah Vivan were spotted partying at a private event at PRIVE nightclub in Atlanta recently.

The two card carrying members of the BMC (Baby Mamas Club ) partied the night away and both looked?absolutely amazing as they popped bottles and smoked hookahs all night long.

[FYI: For those of you who don’t know (or care) Christina is the The Dream’s ex-wife/mother of one of his kids and Sarah is one of Lil Wayne’s many baby moms. ]
