Jewel and Ty Murray can finally start painting their nursery.
“We would have been happy either way, of course, but we are so excited to be having a little boy,” the singer, 36, tells PEOPLE.

“I have to admit, I was doing a little dance on our way out of the doctor’s office when we found out!” says Murray, a nine-time World Champion rodeo cowboy.
