Toni Braxton has been hospitalised. The 48-year-old singer was said to be in a serious condition in hospital related to her battle with lupus and has been in a medical establishment in the Los Angeles area for four days. According to TMZ, she was checked out by a doctor in Atlanta before heading to LA, where she was admitted to hospital for treatment. Toni is currently dating Cash Money Records CEO Birdman and he is said to have jumped on a plane in New York, where he is touring with his protegee Jacquees, to be by her side. However, her representative has insisted she wasn't in a "serious" condition and is now "fine" and back home. They told PEOPLE: "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. "She was not in serious condition, though lupus is a serious disease and must be monitored at all times." The 'Un-break My Heart' hitmaker is planning to start rehearsals soon ahead of her upcoming tour. The rep added: "She has been released and starts rehearsals for her upcoming tour this week." Toni revealed in November 2010 on CBS News that she had been diagnosed with autoimmune disease lupus, which is potentially life-threatening. Her uncle died of complications from the disease and her brother is also a carrier. She was hospitalised back in December 2012 due to "minor health issues" related to lupus.
