Toni Braxton's Las Vegas show remains dark

Will return June 6 at Flamingo

LAS VEGAS -- A hotel official says Toni Braxton's show at the Flamingo Las Vegas won't resume for at least another month.

Harrah's Entertainment spokeswoman Deanna Pettit says the target date to resume the show, "Toni Braxton: Revealed," is now June 6. The Flamingo is offering refunds for canceled shows.

Braxton's show has been dark since the 40-year-old entertainer was hospitalized overnight April 7 with what hotel officials said was a complaint of chest pain.

Pettit says she can't comment about Braxton's medical condition. Braxton has been treated in the past for pericarditis, a viral inflammation of the heart.

Braxton is a six-time Grammy winner for songs including "Un-break My Heart." Her two-year run at the Flamingo Las Vegas hotel is scheduled to end in August.
