It appears that 17 is an unlucky number for Mark Steines -- last year he left his hosting job at "Entertainment Tonight" after 17 years, and now he's split with his wife, former Miss America Leanza Cornett, after the same amount of time.

US Weekly was the first to report the news.

"After a great deal of thought and consideration, we have decided to dissolve our 17-year marriage," the couple said in a joint statement to the mag. "At this time our concern is for our boys as we help them with this difficult transition. We ask that you respect our privacy during this difficult time."

The pair married in Hawaii in July of 1995 and has two sons together, Kai Harper, 10, and Avery "A.J." James, 9.

Steines, 48, currently co-hosts the Hallmark series "Home & Family" with Cristina Ferrare. Cornett, 41, was Miss America 1993 and acts occasionally, having appeared on shows like "CSI" and "Weeds."
