Toni Braxton's Las Vegas stage return has been delayed again after the singer canceled a string of shows last month due to a prolonged illness.

The R&B singer, who has a heart condition, was set to return to the stage on May 6, but has put off headlining her Toni Braxton: Revealed show for at least another month, according to reports.

The star scrapped shows at the Flamingo Las Vegas on April 7 after she was briefly hospitalized with chest pains.

The 40-year-old is said to be desperate to get back to the show as her run at the Las Vegas venue is due to end in August.

A representative for Grammy-winning Braxton refuses to comment on her medical condition.
