Last month, Tom jetted to Las Vegas for work and didn't return home when he initially said he would, which sent Nicola into a frenzy.
Mum-of-two Nicola logged onto Twitter and began begging Tom to come back to the UK, saying that she and their young sons were missing him.
Tom did eventually return, however a source has since told Reveal magazine that the stress of it all caused Nicola to collapse. She was admitted to hospital, placed on a drip and kept in overnight.
Since then, the couple have gone to ground, although The Mirror now claims to have footage showing Tom getting close to a mystery woman in a Vegas nightclub.
He has not commented on the claims, although Nicola has been quoted by the newspaper, saying: "I am beyond devastated to say that I have been shown this video and it is 100% of my husband, Tom Williams."
Last night (31 July), Tom tweeted a picture of the cartoon character Garfield throwing a screwed up piece of paper in the bin, with the caption: "Your opinion has been duly noted."
Alongside it, he wrote: "Lots of these floating around right now - shame you don't know what you're talking about."
Nicola retweeted his post alongside an emoticon of a monkey holding his hands over his eyes, which is thought to mean 'see no evil'.
We hoped this was a sign the couple were getting back on track, however Nicola has since posted her own inspirational picture message on Instagram.
It read: "Cheaters are cowards that are tempted to chase the fantasy of what could be... Instead of courageously addressing their own self-destructive behaviour and cultivating what is."
Nicola has now deleted the post.
