LOS ANGELES (AP) — Singer Toni Braxton has been hospitalized in Los Angeles.

The R&B performer says in a Tweet on Friday that she’s been hospitalized because of “minor health issues” related to Lupus. A spokeswoman confirmed the hospitalization but had no other details. “But no worries!,” Braxton wrote to fans. “I will be out any day now.”

The 45-year-old singer of “Un-break My Heart” revealed two years ago she has Lupus, a potentially deadly autoimmune disease that killed Braxton’s uncle. She also suffers from a narrowing of the blood vessels in her heart.

Braxton said in a recent “20/20″ interview that doctors told her the Lupus diagnosis meant her performing career would likely be diminished and the disease helped push her into a recent bankruptcy.
