A quarter century after their marriage ended in divorce, Marie Osmond and first husband Stephen Craig pulled a Taylor-Burton and said "I Do" for the second time, surprising fans and friends but as I learned, certainly not her close brother Donny.

"I knew they were back together but had to keep it a secret," Donny told me over the phone on Friday. "My sister is happier than ever and I'm happy her son got to witness it. It's so nice to see her happy again."

And responding to a National Enquirer claim that his 51-year-old sister is looking to have another child, Donny said "no, she is not adopting a baby."
