Wayne Newton and his wife are using a surrogate mother to have their first child, their Los Angeles-based publicist said.
Newton, 60, and his 38-year-old attorney wife, Kathleen, are expecting a girl in May, the publicist said Thursday.
The Newtons celebrated their eighth wedding anniversary Tuesday.
"It's just the best news ever," Tricia McCrone, sister of Kathleen Newton, told the Las Vegas Review-Journal. "It's something they've been planning for a long time and they're so excited."
No other details were released.
Newton has a daughter, Erin, 25, by a previous marriage. This will be Kathleen Newton's first child.
The Newtons live in the southeast Las Vegas valley, where they raise Arabian horses.
He is a headliner at the Stardust hotel-casino on the Las Vegas Strip.
