Donny and Marie Osmond, Utah Valley's own famous singing siblings, will host a television special this Mother's Day at 6 p.m. on NBC.

The special is called "America's Favorite Mom," and Americans can vote through today at www.americasfavoritemom.com for the mother they think should have the title of America's favorite. Donny and Marie will perform during the show and, at the end, reveal which mother won the online vote.

Donny and Marie are preparing to leave on a world tour with the other singing Osmonds. This summer, the duo will perform a few shows at the MGM Grand Hotel in Las Vegas, followed by an eight-month engagement at the Flamingo Las Vegas hotel, beginning in September.
