Four years after 5ive split, Ritchie left the UK and moved to Australia so he could revert to his former life as an unknown face.
Earlier this year, on TV show The Big Reunion, he admitted: "People would recognise me in supermarkets and stuff and go, 'You're from 5ive, what are you doing now?'
"I just remember, every time they asked me that question another little part of me would die.
"It's really nice to blend in and just be a normal member of the public and not have that kind of constant recognition."
But following the success of the programme and tour, 5ive are well and truly back - and Ritchie loves being in the spotlight again!
In November, the boy band will tour the UK together and last month they were the only Big Reunion band to play at Virgin Media's V Festival.
Speaking to us, Ritchie admitted: "The fame and being recognised was never going away, so I'm actually quite happy that I'm back being in 5ive.
"It was kind of running away from it all, but now I can embrace it."
Ritchie's bandmate Abz Love - who headed into the Celebrity Big Brother house days later - however confessed that being in the public eye again was strange.
"I was in Sainsbury's in a little Welsh village and someone asked if I was Abz," he told us.
"For a second I was like, 'Yeah, how do you know that?' It's getting a bit weird. I was used to the anonymity. The mojo is definitely rising!"
Tonight (5 September), 5ive will return to ITV2 for a new mini-series of The Big Reunion, which follows both them and the other bands - 911, Blue, The Honeyz, B*Witched, Liberty X and Atomic Kitten - on tour.
During The Big Reunion On Tour, ex 5ive star Jason 'J' Brown will also give his account of his time in the band and why he chose not to reform with the others.
We can't wait!
