Not getting along swimmingly? Tamar Braxton gets kicked out of the pool area for mocking sister Toni Braxton's lesson in Braxton Family Values' Thursday, May 26, episode, as seen in Us Weekly's exclusive sneak peek.
The We TV preview clip shows the Grammy-winning singer practicing her kicks during a swim class in her pool.
"Learning how to swim can be really embarrassing," Toni, 48, says. She adds, "I had no idea that swimming was such this intense workout. I've heard people say that before, but once you apply it, you go, 'Whoa!'"
However, when Tamar, 39, walks outside to watch the lesson, she doesn't offer much positive feedback.
"Wow, she really does swim like a 2-year-old," quips the mom of Logan, 2. "Lo can swim better than that."
Watch the clip above to see the stern words that Toni's instructor has for Tamar.
Braxton Family Values airs on We TV Thursdays at 9 p.m. ET.
