The DNCE frontman, who is currently dating 'Game of Thrones' actress Sophie Turner and previously romanced Ashley Greene, Demi Lovato and Gigi Hadid, still finds it strange that people are interested in his personal life.

He said: "It kind of comes with what you do. I think you never get used to it. You get a little better at it when there's rumours or you have to deal with random drama--[like] old exes that are dating somebody new. I try to just focus on the good stuff and not obsess over it. It's not as bad as it used to be."

The 'Cake by the Ocean' hitmaker is particularly happy for Demi, who he dated in 2010, and new boyfriend, MMA fighter Guilherme 'Bomba' Vasconcelos.

He added: "On the Demi thing, I see she's happy and I'm happy for her. I met Bomba. He's a good guy."

Meanwhile, the 27-year-old singer admits he is "envious" of his younger brother Nick, 24, for achieving success as a solo artist soon after they decided to disassemble their band, The Jonas Brothers, with older brother Kevin, 29.

He told Gotham magazine: "I'm envious at times, watching his artistry and how he went so quickly into creating music and an album. But I also knew that it was important to take time for myself to be able to figure out what exactly I wanted to do next. It's so easy to just jump right into something and release more music, and it might not be the right fit. Now we're able to support each other from afar."
