We tried for several years, and we didn't think it was going to happen for us." The couple adds, "This is a miracle, and we feel blessed."

The happy couple says that their daughter Ella Bleu, 10, is beyond excited.

The family has been moved by the support from their fans. "We are so moved by the generous outpouring of support and goodwill we've received from people all over the world," the couple says.

Those close to the family say that John and Kelly are not trying "replace" son Jett, who died last year at age 16, with a new baby. A family friend says, "They can never replace him" and that the couple "always wanted to have more kids."
