"It didn't dawn on me he was actually asking," she told Kathie Lee Gifford and Hoda Kotb. "He got on one knee and I still thought we were just talking" about marriage.

"It's not bad being the luckiest guy in the world," said Mike, adding he would like to get hitched "as soon as possible."

That's probably a good idea! Savannah was smitten with Bradley Cooper after he showed up on set to hand deliver her a dozen roses and say congratulations.

"Wait a minute. You just had your ring on a second ago," joked Matt Lauer after the special on-air surprise.

"What? Oh my gosh ... just kidding," Savannah said, lifting her bare hand to the camera before slipping the ring back on.
