Kyle bluntly told Jackie live on air that she was 'five out of 10' as her stomach 'needs a fair bit of work'.
‘I'd give you a five,' Kyle grunted to a mortified Jackie.
‘Ten for the legs and face [but] that whole middle area there, that needs a fair bit of work. Five.'
‘Are you bikini ready? It's 37 degrees on Friday. Will we see you at Wet'n'Wild going down the slide in a white bikini?'
'Probably not', answered Jackie.
'Definitely [not]!' Laughed Kyle.
But Jackie managed to get her own back when she told Kyle. ‘You'd understand this, [Michael Bublé] said, "The fatter you get the smaller your penis looks". It's probably been a while since you've seen yours?'
'Now why would you say that? So you're fat shaming me now? Kyle retorted.
'I'm never coming back to work again! Get HR down here, they're fat shaming me and talking about my penis!' He laughed.
Despite the friendly banter, Jackie announced her devastating news a few days back, taking to Instagram to detail her split.
'Lee and I, we decided to separate. It's not a decision we took lightly at all.
'We have been so lucky that our separation has been extremely amicable. And I know everyone says that, but we actually have remained good friends throughout all this.'
The couple married back in 2003 and Kyle was one of the key guests at their wedding.
