Alongside LaTavia Roberson, Luckett left Destiny's Child in the midst of the group's success.
The pair felt the group's manager, Beyoncé's father, Mathew Knowles, favored Knowles and Rowland and was not paying them fairly.
After demanding a change in management, they were replaced by Williams and Farrah Franklin.
Luckett and Roberson subsequently filed a lawsuit against Mathew, Beyoncé, Rowland, and record label Sony Music, accusing them of breach of contract, defamation, libel, and fraud, according to Rolling Stone.
The lawsuit was settled out of court in 2002, just after Luckett and Roberson had started their own group, Anjel.
When the venture failed, the two singers moved on to pursue solo careers.
Luckett has since released three solo studio albums, the first of which, 2006's "LeToya," topped the Billboard 200 and was certified platinum.
Now a thriving actor, Luckett recently had a recurring role in the second season of Starz hit "Power Book III: Raising Kanan."
