Matt Goss says he has spent 'years and years' trying to get to the bottom of his 'complicated' relationship with twin brother Luke.
The pair were inseparable as youngsters and formed a chart-topping pop band with friend Craig Logan when they were just schoolboys in the 1980s.
But relations between the pair turned volatile and the brothers have been honest about not always seeing eye-to-eye.
One fiery row the brothers had came during their reunion was shown in their 2018 documentary Bros: After the Screaming Stops.
As he was announced on the line-up for the upcoming series of Strictly Come Dancing, Matt said he doesn't want "a reclusive life" and appears to be sticking to his word as he opened up about his personal struggles in a bombshell new interview.
Speaking about his family, Matt, 53, said his relationship with drummer Luke remains 'complicated'.
Matt, who shot to fame alongside his brother in Bros, added: "I would do anything for Luke. If we both feel a little bit wobbly or vulnerable, we're there for each other certainly.
"But we know each other so well we know exactly where each other's buttons are.
"I can honestly say I never want to p*** Luke off, but I have a way of being able to and he has a way of being able to with me," he told the MailOnline 's Weekend Magazine.
Matt went on to describe drummer Luke as the 'backbone' of the band but said he had often felt guilty about stealing the limelight as the charismatic frontman.
"I felt I had to apologise for being the frontman for three decades. Those days are over," he vowed.
All eyes are sure to be on Matt as one of the contestants on this year's Strictly.
He will be joining a star-studded line-up that includes Kym Marsh, Tony Adams MBE, Molly Rainford, Ellie Taylor, Matt Goss, Tyler West, Ellie Simmonds, Jayde Adams, Richie Anderson and Kaye Adams.
EastEnders James Bye, singer Fleur East and actor Will Mellor have also signed up.
Speaking on BBC Breakfast this week, Matt said he wants the UK to see more of him.
"It is a nice feeling to have - that familiarity with the British public. It’s very conversational," he said.
"There’s selfies and we’ll chat about life and that’s the life I want. I don’t want a reclusive life in my place, I want to get out and embrace life much more than I have done and obviously with my announcement yesterday, it’s as public as you can get really."
"I’m used to singing in front of anyone you can imagine - Mohammad Ali to the President of the United States - I’ve done so much and to get butterflies about something is a good feeling."
The singer-songwriter sold most of his belongings ahead of his transatlantic move, although he did keep his art and crystals.
Matt went on: "There’s a lot of stuff to arrange in my mind but it’s something that I needed to do for myself. I’ve gone to that place, the beautiful unknown, and I want to truly I believe in my own philosophy that the unknown is something to look forward to."
