Rhodri Giggs and the Celebrity Big Brother contestant were photographed by The Sun taking a stroll together arm in arm, with a source giving credence to the apparent reconciliation by saying that the couple are "determined to patch things up".
"They're determined to make it work. They still love each other," the insider said. "There isn't a lot of love for Ryan from either of them - but they clearly have love for each other.
"You wouldn't think they were a couple who've just been through a living hell. They look like people who just started dating."
Rhodri is believed to have moved back into the pair's marital home in Bolton, where Natasha has been living with their 5-year-old son Louis and her 10-year-old son Liam, her child from a previous relationship.
"Rhodri is back at home," the source claimed. "Natasha wants him there. He wants to be there. They are talking things through. But I don't think they will ever be friends with Ryan again."
The former couple have both expressed an interest in getting back together recently, with Rhodri admitting in a series of interviews that he still loves Natasha.
Rhodri has suggested that Ryan had no qualms about the affair because he believed himself to be "untouchable".
