Merriman -- who turned 30 today -- said he made his proposal atop a tower overlooking the city's harbor against the backdrop of a New Year's fireworks display. "I did it on the fly of the moment. Thank God it worked," he said. "As soon as I gave her a kiss and proposed," he continued, "the fireworks started going off. It was kind of like a movie."

The actor remained mum about any specific plans for the nuptials. "You know it's her day," he said. "I'd marry her on a beach. I don't care. We could go to Vegas. But she's a very classy one so... 'If mama ain't happy, ain't nobody happy.'"
