Yogita Tailor, 29, received a big surprise when her boyfriend of two years, Dhaval Desai, asked her to marry him in the crowd outside the " Good Morning America" Times Square studio today.

"The past two years have been amazing and I want you to know how much I love you. Nothing would make me happier than to spend the rest of my life with you," Desai, also 29, said on "GMA" today.  "So as we stand here in the heart of New York City, in Times Square, on 'Good Morning America,' with all of our friends and family watching, there's something I want to ask you. Baby, will you marry me?"

"Oh, my gosh, yes," she squealed, smiling.

Desai and Tailor, both doctors who are finishing their residency training in different cities, met on Match.com and have been dating long distance for two years; he lives in Dayton, Ohio, and she in Baltimore. When Desai planned a trip to New York City to celebrate Tailor's 29th birthday, she knew there would be surprises in store, but never suspected a proposal.

"I was shocked. I had no idea this was coming," she said. "He had so many surprises for me for my birthday. The whole week was a big surprise overall. I didn't ask any questions. I just said, 'I'm going to let him run with it.'"

Desai, a loyal "GMA" fan, contacted the show to bring his idea for the big-city proposal, live on TV to life. "I was looking for something bigger," he said.

Close family and friends were in on his proposal plans, but Desai was under pressure to keep it all hidden this week from his now-fiancee. "I was nervous. I got two hours of sleep last night. I was tossing and turning, thinking about what to say," he said. "This was the hardest secret I've ever kept."

After the proposal, the couple was giddy with the engagement news. "Yogita is just getting off the phone with her mom," he explained.

Too early to talk wedding details, Tailor said she knows their wedding will fuse their Indian and American culture. Both come from traditional Indian families.

The live television proposal was not the last surprise Desai has in store for his bride-to-be. The couple will leave New York City and head off together to celebrate "somewhere warmer," Desai said, adding to Tailor's delight.

"He's been so amazing," she said.
