"He proposed and showed me the ring and I was so shocked and said, 'Omgod,' and I hugged him and he said to me, 'So is that a yes?'" said Bowden, who was still blindsided even though they'd previously discussed getting married.

Bowden, named Esquire magazine's 2011 "Sexiest Woman Alive," wore a strapless champagne sheath gown with a floral beaded tulle overlay by Amsale to the SAGs.
