Kevin Jonas will be trading in his purity ring for a wedding band.

The eldest member of the Jonas Brothers proposed to his girlfriend, Danielle Deleasa, on Wednesday morning, according to People. Jonas, 21, popped the question to 22-year-old Deleasa, a former hairdresser, at her New Jersey home with a cushion-cut diamond ring he designed with Jacob & Co.

Jonas flew overnight from a performance in Vancouver to make his proposal. "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 told the magazine.

Jonas' parents, Denise and Kevin Jonas Sr., said in a statement that their "hearts are filled with joy," and it "is such a blessing that [Danielle] will be joining our family."
