According to reports, the bandmates, who previously dated for five years in the past, have split once again, due to their "busy schedules" putting strain on their relationship.
Hannah and Paul decided to give their romance another shot, after being reunited on S Club 7's reunion tour earlier this year. However, things haven't worked out for the pair and recently, Hannah and Paul called time on their relationship, but insist they have stayed the "best of friends".
A source told The Sun: "Hannah and Paul had been apart for so many years and their chemistry came straight back on the tour, but they both have different lives now and are doing different things... They decided mutually that they would go their separate ways."
News of the pair's break up will come as a shock to fans, as Hannah had gushed she and Paul were "really happy", after getting back together and moving in with each other.
Hannah had been engaged to personal trainer Adam Thomas, prior to reuniting with Paul, and he claims Hannah kicked him out of the flat they were sharing together, to move Paul in.
He then hit out at Hannah for slamming Paul in the past as the "fat one who can't dance", but she denied this was ever the case, insisting "no one could ruin" what she and Paul had.
"The reaction from fans has been great," she added "We've had lots of messages from people saying they glad we're back together. It's so nice."
So far, Hannah and Paul are yet to comment on their split.
