Nick Jonas insists there is no bad blood between him and his brothers.

The 21-year-old singer says his older siblings, Kevin, 26, and Joe, 24, who disbanded their squeaky clean band, The Jonas Brothers, last year, were the first people to hear his new single 'Chains' and are ''very supportive'' of his solo career.

He said: ''They heard it before everyone else did. They loved it. They were really positive. It was great to feel that from them. They all have their things going on as well.''

He added: ''We're supportive for each other till the end.''

Despite still being on good terms with his former bandmates, Nick admits he had some fears about going out on his own.

He told E! News: ''There are moments when you sort of question yourself like anything and wonder if you're making the right move forward, but I feel like the minute I really started creating, I came to a place where I was locked in and felt like I was making the right move, pushing myself and continuing to be around people that make me better. And it's been a great process. I'm really looking forward to people hearing the whole record.''
