Osmond Reunion in Sin City

The long-rumored Osmonds reunion will be in Las Vegas this summer, with a Aug. 13-14 50th anniversary PBS special at the Orleans Arena.

The musical mormons , who churned out teenybopper hits in the 1970s, haven't performed together in 25 years.

Teen heart throb Donny Osmond, who turns 50 in December, will be joined by sister Marie and most of his singing brothers.
