Nick Jonas and Demi Lovato go bowling together.

He said: "We usually go bowling. I've got my own ball and shoes and everything so I'd say probably I'm the best bowler. I'm very serious about that.

"We genuinely love just hanging out and playing music. It's great just to have no agenda but to vibe out."

Despite forging a solo career away from his brothers and Jonas Brothers bandmates Joe and Kevin, Nick has stayed close to his siblings.

He said: "We try and see each other as much as we can. Kevin is in New Jersey with his wife and baby so I try to get out there and visit.

"Joe and I see each other quite a bit in LA. We're very close."

But Nick admits he initially found it "hard" working alone.

He added to heat magazine: "There are moments where I've had to adjust to it just being me. I wouldn't necessarily say that I get lonely but it is a big adjustment.

"Also, in press and things like that, it's all on me now, instead of being able to spread it out."
