The Jonas Brothers are well-known for their sibling bond [1], but there's one member of their extended family we need to talk more about. After Kevin married his wife, Danielle [2], he gained a few new siblings, including a brother-in-law named Mike Deleasa [3]. If you're a longtime fan of the Jonas Brothers, then you're probably already familiar with the handsome 31-year-old.

In addition to making multiple appearances on Kevin and Danielle's E! series, Married to Jonas, he also went on the road with the Jonas Brothers. Before they broke up in 2013 [4], he served as the opening act for their South American tour dates. In 2014, he released an EP titled Lil' Something [5] under the name Deleasa, but more recently, he has worked as a DJ and creates music under the name 5x8 [6]. As the Jonas Brothers step back into the spotlight with their recent reunion, get better acquainted with Kevin's brother-in-law by scrolling through some of his best snaps.
