Jeffrey Mayer/WireImage.com Toni Braxton is still on the mend.
The R&B diva won't be returning to her long-running show at the Flamingo Las Vegas for at least another month, after what was initially supposed to be a three-week break for health reasons, according to a rep for Harrah's Entertainment.
Toni Braxton: Revealed is scheduled to close in August, but the titular star hasn't been onstage since she was hospitalized with chest pains on the evening of April 7.
No one is commenting on her current medical condition, but Braxton has been treated in the past for pericarditis, an inflammation of the lining of the heart.
Donny and Marie Osmond have inked a deal to put on a greatest-hits-style variety show once Braxton's two-year run at the Flamingo ends.
