LAS VEGAS (AP) - Producers of Donny and Marie Osmond's Las Vegas Strip show say the brother-sister duo is extending a contract with the Flamingo resort.

Officials with the casino say tickets are on sale for performances running from February through June.

Marie Osmond said in a statement that she's thrilled to have the residency extended. She said she and her brother signed a six-week contract in 2008 but never expected it to become a multi-year run.

The duo's 90-minute live show features music from their five decades of entertaining.

Tickets range from $95 to $260.
