Tamar Braxton may have to cough up some big bucks! She's being sued by a young woman named, Emmi Kozulin, who claims Tamar stole her song for her album "Love & War"

Kozulin states in the lawsuit that  she wrote a song titled “One on One Fun” with songwriter Angela Hunte. The deal was they would both get credit for the song.

She says she wrote with Hunte and then recorded the song they wrote on her own. The two never made an agreement or signed any paperwork regarding who owns the song.
