In the latest episode of the reality show, viewers saw Pete unveil his new inking - an 'M' initial to pay tribute to girlfriend Megan. Pete's tat was part of his plan to win Megan back (they have been taking some time out, after he was caught texting other girls behind her back), but Tommy made light of his gesture following the episode.
He decided to draw on his own tattoo, a 'G' initial, because of girlfriend Georgia Kousoulou...
Tommy's DIY inking was done with a biro pen and sharing a photo of it to his Instagram page, Tommy added the caption: "They forgot to show my tattoo as well man. Biro gang," along with a slew of crying with laughter emojis.
Since posting 11 hours ago, Tommy's snap has been liked over 14,000 times and fans have been quick to comment.
One user said: "Lol @tommy_mallet you are such a piss taker but I love it," while another added: "That's so funny."
Another referenced Tommy's mission to land himself an OBE from the Queen and commented: "OBE worthy."
Neither Pete or Megan have appeared to respond to Tommy's latest Instagram post, but we're itching to know what the pair make of it, you?
It's not the first time the couple have had their co-stars take the mickey, Dan Edgar and Diags had re-created a naked selfie Pete and Megan took during a holiday to Barcelona.
Pete and Megan took it in jest and after seeing their efforts, Megan had joked: "Diags' ball bag is hanging out!"
Tommy mocking Pete, meanwhile, comes after Pete debuted his new 'M' tattoo onscreen.
Lockie had been the one to reference it first, telling his best pal that he had a "bone to pick" with Pete over his inking.
Lockie said: "I've got a bone to pick with you, there's something I'm a little pissed off with. I've been your pal for a good few years now. Megan's been on the scene six months and you've gone and had another tattoo on your arm. What's that about son?"
Pete replied: "[Megan] didn't know I was doing that either. It was supposed to be a bit of surprise for her. If things don't work out I'll put a U and a M next to it for mum."
"Or put U G on the end," Lockie joked.
