Lifetime's biopic "Toni Braxton: Unbreak My Heart" aired Saturday night, and the 48-year-old singer and her sisters live-tweeted along with the audience to share their thoughts on the movie. In a since-deleted post, Toni's youngest sister Tamar Braxton wrote to a fan that some of the events in the two-hour movie were "not real."

In one particular scene, Toni sat her family down to tell them that producers Babyface and L.A. Reid didn't want to sign the Braxton sisters as a group; they only wanted to sign her as a solo artist. According to the Lifetime movie, Tamar took the news the hardest and stormed off worried that she would never become famous.

According to The Shade Room, Tamar tweeted about the scene to a fan writing, "It's a MOVIE not REAL or the way I recall a few things... but I was a hater at 11."

It's long been rumored that Tamar was jealous of Toni's musical success, something the 38-year-old adamantly denied.

Tamar later deleted the post, writing instead, “Jokes aside… I’m really enjoying this movie #goodjobsissy @tonibraxton and @towandabraxton [I’m] so proud 2 b apart of your amazing journey.” 

On Instagram, "The Real" host continued to praise her big sister writing that she has always been Toni's "biggest cheerleader."

"I love you. I’m so proud of you and everything you have in front of you," she posted. "You will always be my heart — Always.” 

Some of Toni's other sisters also commented on the movie, including Towanda Braxton and Traci Braxton. Check out their reactions below:

“I was stronger than I thought I was,” she said. “I’m pretty proud of myself. I can’t deny it.”
