The pair reunite over the weekend
The pair were both dressed down in grey joggers and loose tops and sported matching trainers, although they were in different colours.
On Sunday, Katie – who Kieran admitted to cheating on with her best friend Jane Pountney in May – focused on her unborn daughter at her baby shower.
Around sixty guests are believed to have joined Katie at her Sussex home, where a 4D baby scanning van was photographed arriving from Loughborough.
It sounds like she had a rather interesting day planned for the male attendees.
‘Does anybody know where I can higher pregnancy suits for men please for my baby shower this weekend xx,’ Tweeted Katie last week.
