Is one of Toni Braxton's sisters trying to steal the singing spotlight?

Tamar Braxton, star of "Braxton Family Values" and "Tamar and Vince," has released her first single "Love and War" today ... and, we gotta admit, she's got a great voice.

The song is a silky R&B tune that let Tamar's vocals shine and it's already got a celebrity fan: Lady Gaga.

"K I NEVER PROMOTE ARTISTS but if u want your mind blown check @tamarbraxtonher "Love & War" She's Toni Braxton sister + her voice is BEYOND," Gaga tweeted moments ago.

She's not just a fan though, she's also a friend.

"MYSELF AND @tamarbraxtonher have been the best of friends since her husband Vincent discovered + signed me when I was 20. SHE IS INCREDIBLE," Gaga added.
