The hunky singer – who admitted his bisexuality in a newspaper interview last year – can't wait to receive admiration from both male and female admirers when he plays his first concerts since revealing his sexuality.
When asked if he was excited about receiving female attention when the boy band return later this year, Duncan laughed and said: "And male attention please!"
The singer believes he will enjoy performing with Blue – also comprising Lee Ryan, Simon Webbe and Antony Costa - even more now he is open about his sexuality.
He said: "For me after coming out in the press last year I've got a weight off my shoulders and I'm going to enjoy coming back in to Blue. I won't be worrying about stuff, I'll be comfortable in my own skin".
Duncan – who has a five-year-old daughter Tianie-Finn from a previous relationship – is currently single but thinks his work makes it difficult to find love.
He explained to BANG Showbiz: "I am single at the moment. It's really hard to meet people in this business. Your schedule is different, you're working different hours so you can't just go out on a Saturday or Sunday night and meet people."
