In an interview with NME about selling his prized possession, he took the opportunity to throw shade at bandmate Jo O’Meara, who joined the group when it was S Club 3.
"Me and Bradley were doing it for about two years -- and then Jo came along," he said. "That bully from Essex came along and bullied her way into the situation."
"'You know what I am, Paul -- I'm the anchor in this band,'" Cattermole recalls O'Meara saying to him. "I think you missed a W there! No, I'm half mucking about, half serious. We do actually get on."

"Not everyone in the band sees eye-to-eye," he explained. "There was a fall-out other whether we should be doing a dance troupe, Diversity-type show with choreography to backing tracks, or do what we've always done and have a live band."
Those hoping to see Cattermore on tour with the group later this year will be disappointed, too. He says that he has been replaced by Tina Merritt.
