The dance act, who rose to fame after winning 'Britain's Got Talent' in 2009, are still in touch with other acts from the talent show but admit they don't see much of the show's boss.
Group member Jordan Banjo told BANG Showbiz: "In our year there was Flawless, another dance act, and we see them from time to time, they're really cool guys. It's really cool to see everyone from our year still going and still doing really well.
"[But] we don't see Simon Cowell that much. I'm going to be honest, he doesn't just pop out for lunch with us, but anytime we do see him he still says he loves what we do and he really enjoys it [watching us perform]."
Jordan feels the group were lucky to be able to make a difference to the UK street-dance scene and make money from their talent, as well as have support from family and friends during their time on the show.
Asked if he would give any advice to this year's contestants, he said: "There's certain times that there's going to be a lot of pressure. I think if you're a solo act in a show like 'Britain's Got Talent' it's always going to be really, really difficult.
"If I had any advice it's just to make sure your friends and family are around you and just do what you do best."
Diversity will be performing at UK Live, headlined by McBusted, in Weston-super-Mare on Saturday, June 28, and in Ipswich on Sunday, June 29. Visit uklive.co.uk for tickets, including combined packages for both days.
