Kevin Jonas Is Engaged!

Kevin Jonas surprised his girlfriend Danielle Deleasa by showing up at her doorstep in New Jersey early Wednesday morning and dropping down to his knee to ask her to marry him. Presented with a cushion-cut diamond ring that Jonas designed with Jacob & Co., Deleasa couldn't believe what was happening.

Then, "She said yes, yes, yes like 500 times super fast in a row," the oldest of the Jonas Brothers tells PEOPLE exclusively.

Jonas, 21, and Deleasa, 22, who met in May of 2007 while vacationing with their families in the Bahamas, haven't set a wedding date yet. "It still feels like a dream," she tells PEOPLE.
When Deleasa, a former hairdresser, first met Jonas two years ago, she admits, "I didn't know who the Jonas Brothers were." It was Kevin who eagerly pursued her after meeting her and then spotting her walking on the beach with a flower in her hair.
