*Tamar Braxton is being sued by a songwriter who claims the singer stole one of the songs on her new album … and even stole her vocals.

According to TMZ, Emmi Kozulin claims she co-wrote “One on One Fun” with Angela Hunte. Kozulin then recorded a version of the song on her own.

Kozulin claims Hunte gave the song to Braxton for her album “Love and War.” Kozulin admits Hunte had the right to license the lyrics , but Kozulin claims Braxton’s recorded version included vocals from Kozulin’s version – and that crosses the line.

Kozulin claims — as co-writer of the song — she’s entitled to 50% of the royalties … plus damages.

A rep for Braxton tells TMZ the fight is between the writer and producer and, “has nothing to do with Tamar.”
