Kevin Jonas to Say 'I Do'

Things are "Burnin' Up" between Kevin Jonas, 21, and longtime girlfriend Danielle Deleasa, 22 -- and she's got the engagement ring to prove it!

The eldest Jonas popped the question to Danielle early Wednesday morning when he surprised her at her New Jersey home and asked her to marry him! "She said yes, yes, yes like 500 times super fast in a row," Kevin dished to People magazine.

Jonas presented Deleasa with a cushion-cut diamond ring from Jacob & Co. The bride-to-be revealed to the magazine that she's still in shock. "It still feels like a dream," she said.

The Jonas' parents, Denise and Kevin Sr., released a statement about the couple's happy news. "Our hearts are filled with joy today and we are happy to share with you that our son Kevin has asked Danielle for her hand in marriage."

They continue, "Her answer was yes, and it is such a blessing that she will be joining our family. Kevin and Danielle have not yet set a date. Family is very dear to us, and we hope we have raised Kevin to be a wonderful man and husband. Please join us in our family's celebration and in congratulating Kevin and Danielle. Thank you for all of your support."

Kevin's famous siblings also expressed their joy at welcoming a new sister by writing on their Twitter page, "Congrats big brother.....Dani welcome to the family, we can't wait to have you join us on the road!"
