OneWed.com Wedding News - Kevin Jonas getting ready to discard the purity ring

He may be the oldest Jonas Brother, but 21-year-old Kevin Jonas seems a bit young to be wedding planning.

Still, the teenage heartthrob told People.com that he and his girlfriend Danielle Deleasa are engaged and ready to take the leap into matrimony.

According to the website, Kevin took an overnight flight from Vancouver and showed up on his girlfriend's doorstep with a diamond engagement ring he designed with Jacob & Co.

The singer then dropped down on one knee to pop the question to the amazed Danielle, who told People "it still feels like a dream."

"She said, yes, yes, yes like 500 times super-fast in the row," Kevin added, after confessing that he had been distracted during a concert the previous night by thoughts of the proposal.

All three Jonas Brothers - Kevin, 19-year-old Joe and 16-year-old Nick - wear purity rings and have spoken about their commitment to remain virgins until marriage.

With that in mind, it is easy to imagine that Kevin may be "burnin' up" to walk down the aisle promptly.
