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.
