Veteran pop star Donny Osmond is set to become a grandfather for the sixth time.

The Puppy Love hitmaker welcomed his fifth grandchild last month (Jan13), when his son Donald, Jr. and his wife Jessica became first-time parents to a son named Truman Clark.

And now he's revealed the Osmonds are expecting another new addition to their growing brood.

The proud singer showed off a photo of the newborn during an appearance on U.S. chat show The Talk, which aired on Friday (22Feb13), and announced, "Since that baby was born, my son Jeremy and his wife announced that they're gonna have their third baby so number six is on the way!"
