Jim Spellman/WireImage.comToni Braxton is unbreaking her headline run and letting her health take center stage.
In the wake of her brief hospitalization for chest pains last week, the Grammy winner has called off all remaining April dates of her Las Vegas showcase, with no plans to resume performing until at least May 6.
The 40-year-old is technically nixing only one week's worth of concerts—the cancellations come in advance of a previously planned two-week hiatus for Toni Braxton: Revealed—but her three-week hiatus will allow her to rest and undergo more medical testing in connection with her hospitalization.
While the exact cause of her overnight stay at Sin City's St. Rose Dominican Hospital was not disclosed, upon her release she copped to having suffered from chest pains.
Braxton has previously admitted to suffering from pericarditis, an inflammation of the lining of the heart, which she was diagnosed with four years ago. The R&B star has said side effects include periodic heart flutters and high blood pressure.
Braxton has been headlining at the Flamingo since August 2006. Refunds are being offered for the scuttled gigs.
