The former glamour model spent the weekend with her family, and later uploaded a snap of herself and Kieran showing off their tummies.
Katie and Kieran err, strike a pose
Katie and Kieran are both laughing in the snap, with chocolate eggs balancing on their stomachs, which are looking rather different.
In the accompanying caption, Katie jokes: "Look at our six packs and summer bodies".
That hasn’t stopped Katie from discussing Kieran’s well-documented cheating though, and she’s discussed his affair with her former pal Jane Pountney a number of times.
Katie and Kieran, as we're used to seeing them
“I know Derrick and Jane are divorcing,” she revealed in March. “Whatever she did I will never forgive her, and I'm just so glad her life is ruined.
“It's weird, Derrick and I have never been angry at Kieran, it's more Jane we're shocked by. I think because she'd dramatically changed.”
