The 45-year-old 'Un-Break My Heart' hitmaker, who opened up about her struggle with lupus last year, is now suffering from the auto-immune condition which attacks healthy body tissue.
This has left her in need of medical attention, reported Daily Star.
The singer took to Twitter to tell fans about her hospitalisation.
"Hey guys, I am in the hospital for health issues related to lupus & blood clots, I will be home soon. Thanks for all the love & support," Braxton posted.
This is the second time the R&B star has been hospitalised due to the illness this year. She was also admitted to a clinic in January after her immune system started to shut down.
Braxton also suffers from heart condition microvascular angina.
