*Toni Braxton's return to the Las Vegas stage has been delayed again. She'll remain sidelined from her headlining show for at least another month, reports the Associated Press.

      Harrah's Entertainment announced Friday that it now expects to resume "Toni Braxton: Revealed" at the Flamingo Las Vegas hotel on June 6.

      The show has been dark since the singer was hospitalized overnight for chest pain on April 7. The Harrah's spokeswoman says she can't comment about Braxton's medical condition.

      Braxton, 40, has been treated in the past for pericarditis, a viral inflammation of the heart.

      Braxton's two-year run at the Flamingo Las Vegas is scheduled to end in August.
