Paul Kevin Jonas II (born November 5, 1987), also known as Kevin Jonas, K2 and is a member of the Jonas Brothers, a band he created with his younger brothers Joe and Nick. The Jonas Brothers originally started with a solo singing career for Nick , but when Joe and Kevin sang backup for him, the record producer liked their sound and signed all three of them.

Kevin Jonas was born in Teaneck, New Jersey to Denise and Paul Kevin Jonas Sr. He was raised in Wyckoff, New Jersey and is of Irish, Italian, German, and Cherokee Indian descent. The Jonas's are known for their wholesome, family-friendly image. The brothers are all committed Evangelical Christians, their father is a former pastor, and they were homeschooled by their mother. In addition, they all famously wear purity rings on their left-hand ring finger and have vowed not to have premarital sex. Joe has said that the rings symbolize "a promise to ourselves and to God that we'll stay pure until marriage, and Nick had stated that "the [purity rings] are pretty awesome, and the rings are just one of our ways of kind of like being different than everybody else out there." They started wearing the rings when their parents, Denise and Kevin Sr., asked them if they wanted to. They also abstain from alcohol, tobacco, and drugs.
