The singer's daughter, Rachael, is pregnant with her first child.

Announcing the news during a guest co-hosting stint on U.S. show The Talk on Monday (04May15), Osmond said, "Rachael, my daughter, is gonna have a little girl!"

Osmond, 55, is making a habit of sharing family news on The Talk - she previously announced her son Stephen was to be a dad in June, 2013, and introduced her first grandchild to the world by carrying him out onstage during a return visit to the daytime show in January, 2014.

Rachael is Osmond's daughter from her former marriage to Brian Blosil.
