Nick Jonas hangs out at home in his underwear.
The 22-year-old hunk has admitted he isn't keen on wearing too much clothing in the comfort of his own home and usually struts around in just his boxer-briefs.
The star told Billboard magazine: "In my apartment by myself, it's usually just me in my underwear."
Nick has recently been linked to model Kendall Jenner, but it's thought the pair are taking things slowly.
A source close to the 'Jealous' singer said: "Nick and Kendall are hanging out, but it's nothing that serious, as Jonas just got out of a relationship and isn't looking for anything major at the moment. He is really focusing on his career at this time."
The duo have enjoyed a "few dates" in recent weeks after being introduced by Nick's older brother Joe, 26, who is dating the 19-year-old model's best friend Gigi Hadid, 20.
The insider told E! News: "He enjoys hanging with Kendall when they are both in the same city, and it's nice because they have a similar group of friends (and family) in common."
