"Toni is resting at home and she is fine. She was in an L.A. hospital for a few days being treated for her lupus," her reps said in a statement to ABC News.
"She has been released and starts rehearsals for her upcoming tour this week. She was not in serious condition, though lupus is a serious disease and must be monitored at all times," Braxton's representatives added.
Lupus is a chronic, autoimmune disease, causing inflammation to a person’s internal organs, joints and skin. Lupus is not contagious and may be caused by a number of factors, including hormones, genetics and one’s environment, according to the Lupus Foundation of America. An exact cause for the disease is still unknown.
Many fans of the Grammy award-winning artist, 48, first learned about Braxton's battle with lupus in 2011, when she revealed the nature of the disease to her family on their hit reality television show, "Braxton Family Values."
She also appeared on "The Dr. Oz Show" in 2013 to talk about her diagnosis.
