Inside Wayne Newton's Palatial, 52-Acre Las Vegas Mansion

Wayne Newton's Las Vegas estate might as well be the Smithsonian of Sin City and ET guest correspondent Antonio Sabato Jr. got to look inside!

"I couldn't be more thrilled to have you here," Newton said, welcoming Sabato Jr. into the 52-acre Casa de Shenandoah.

The sprawling ranch, now open to the public, includes paintings by Renoir and Margaret Keane, a small zoo filled with exotic birds and a capuchin monkey named Boo, who was remarkably attached to Newton on his private jet.

While inside Newton's 165-seat theater, the legendary entertainer explained what the property means to him.

"What's happening is the fulfillment of a life-long dream," Newton said.

That dream includes a stable that houses 60 horses. Vegas provides a suitable climate for the Arabian breed that gallops through the ranch, and they even have a swimming pool to train in.

"One time around this pool would be equivalent to five miles at a hand gallop on the track with no stress at all on their legs," Newton said.

Newton's office is called the Red Room, which contains mounds of memorabilia, from presidential letters to Robert E. Lee's sword.

"You could actually take a week and never see everything in this room," Newton said.

Fans can get an up close and personal look at the memorabilia, house, jet, cars and exotic animals as the lavish property is now a museum with tours starting at $35.
