Kevin Jonas surprised his girlfriend Danielle Deleasa Wednesday morning by knocking on her New Jersey door and dropping down to his knee to ask her to marry him.

Then he handed her a cushion-cut diamond ring that he helped design with Jacob & Co.

Her response?

]]>Musicians_Jeffr_16635386_600 "She said yes, yes, yes like 500 times super fast in a row," the oldest of the Jonas Brothers tells People.

Jonas, 21, and Deleasa, 22, who met in May 2007 while vacationing in the Bahamas with their respective families, haven't set a wedding date. Give them time!

The former hairdresser admits that, when she first met Kevin, she didn't know who the Jonas Brothers were. Kevin pursued her after seeing her walking on the beach with a flower in her hair.

Note to self: Practice wearing flowers nonchalantly in hair on tropical vacations.

Jonas flew to NY from Vancouver to pop the question. "It was tough performing last night, knowing that I was going to ask the biggest question in my life to the most amazing girl in the world," he admits.

Soooo romantic!!!

Are you sad or happy? Tell the truth.

And which Jonas Brother will be next?

Funny that the JoBro with the stable relationship is the one dating a noncelebrity girl. Take a hint, Joe and Nick!
