Toni Braxton's iconic music career, family struggles and past money issues will be chronicled in the upcoming Lifetime original movie "Toni Braxton: Unbreak My Heart." The two-hour long film, which premieres Saturday at 8 p.m. EST, stars up-and-coming actress Lex Scott Davis as the 48-year-old singer.

"Toni Braxton: Unbreak My Heart," based off  of her 2011 memoir of the same name, will begin with Toni signing to L.A. Reid and Kenneth "Babyface" Edmond's label LaFace Records.

The “Braxton Family Values” star has often said that her big break in the music industry led to her feeling guilty because her sisters, Tamar, Trina, Towanda and Traci Braxon were not picked up by the label even though they had been singing together as a group since they were children.

The Lifetime movie will show how the family dealt with Toni's record deal, as well as the singer filing for bankruptcy, her divorce from musician Keri Lewis and her public battle with Lupus.

“It was important to keep it vulnerable and honest, a compelling but loving story,” Toni told Billboardabout the film. "But I didn’t want to be a victim. It was just as important to talk about things I’d done to hurt others either knowingly or unknowingly."

The Lifetime movie also stars "Guiding Light" actor Gavin Houston as Babyface, "Power" star Debbi Morgan as Toni's mom Evelyn, Cortney Scott Wright as Traci, Skye P. Marshall as Towanda, LaToya Franklin as Trina and "Devious Maids" star Tiffany Hines as Tamar.

"Toni Braxton: Unbreak My Heart" premieres Saturday Jan. 23 at 8 p.m. EST on Lifetime.
