LAS VEGAS - Four more Toni Braxton shows have been canceled as she recuperates following her hospitalization with chest pain. "We're going to go ahead and cancel her shows tonight and for the rest of the week," Flamingo Las Vegas hotel-casino and Harrah's Entertainment Inc. spokeswoman Deanna Pettit said Wednesday. "We expect she'll return to the stage next Tuesday."

Pettit says the 40-year-old Grammy winner is recovering at home following her release Tuesday afternoon after precautionary tests at a Las Vegas area hospital.

The exact cause of Braxton's chest pain has not been made public. Braxton has been treated in the past for pericarditis, a viral inflammation of the heart.

Pettit says the Flamingo Showroom is offering refunds for the canceled shows.

Braxton is a six-time Grammy winner for songs including "Un-break My Heart." Her Las Vegas act, "Toni Braxton: Revealed," is in the midst of a two-year run at the Flamingo.
