Continuing health problems have forced Toni Braxton to cancel the rest of her Las Vegas show "Toni Braxton: Revealed."
Following an April 7 hospitalization for chest pain, the 40-year-old singer canceled shows at the Flamingo Las Vegas hotel until June 6, when she was scheduled to return, the Associated Press reports.
A spokesperson for Harrah's, which operates the Flamingo Lounge, has confirmed the singer will not return, but would not comment on the singer’s current condition. According to the AP, Braxton's two-year run at the Flamingo ends in August.
In the past, the six-time Grammy-winner has been treated for hypertension and pericarditis, a viral inflammation of the sac surrounding the heart. On April 8 she was released from the hospital after undergoing precautionary tests at a Las Vegas medical facility. At the time, she was said to be recovering at home.
