LOS ANGELES  — 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.”
