But the TV couple’s PDA was all in the name of research as they were debating whether canoodling in front of people is offensive or acceptable.
We’re used to seeing celebrity couples getting touchy feely in front of the cameras - from Kim and Kanye to Posh and Becks - they just can't get enough.
Following recent snaps of Liz Hurley and Shane Warne having a cheeky grope at Ascot, the ITV show polled its viewers on whether they thought PDAs can go too far… leading to a re-enactment from the show’s hosts.
Eamonn and Ruth, both 53, giggled as Eamonn gave his wife’s breast a squeeze and said: ‘The temperature's rising, we can get out of control...'
He said: 'All this touchy feely stuff, kissing, snogging whatever you want to call it, is there any harm in it, is it offensive?
Ruth tweeted later: 'Glad my PDA (Public Display of Affection!) with @eamonnholmes made you laugh this morning....just a bit of fun!'
The mother-of-one recently revealed that in reality, her husband gets embarrassed if she just tries to hold his hand in public.
But he claimed: 'I'm married to a predator and it's very difficult! One thing leads to another...'
At the end of the show it was revealed that 40 per cent of viewers asked found PDA’s distasteful and over 1 in 10 said they’d asked couples to stop, while over half were ‘sick of celebrities cavorting in public.’
