Tamar Braxton performs new single ‘Let Me Know’ live for the first time...

I love great singers! 

Tamar Braxton served up some serious vocals at V-103′s 'For Sisters Only' concert in Atlanta on Saturday. She performed her Future-assisted new single 'Let Me Know,' live, for the first time, and those whistle notes were everything! Even if they were lipsynched, the rest of the performance was live and she aced it!

What would have made the performance better was if she served up a little more energy outside of tossing weave and wining her hips, but vocally, she slayed. Watch her in action below.
