The former TOWIE star uploaded a rather mournful looking picture to Twitter on Tuesday night (29 April) to show just how sad he is when Michelle isn't curled up in bed next to him.
Mark added the caption: "Tired but can't sleep !! My bed feels empty tonight !! Feels like something's missing. Get your ass back here @michkeegan."
He added: "Why is it that when you have to be up so early you can't sleep. Up in 5 hours !! I might just see it through and stay up !!"
While Mark's photo was no doubt aimed at Michelle, it didn't stop his appreciative fans commenting in droves. "Ahh this man is bloody perfection," wrote one, while another simply wrote: "HOTTY!" Quite.
There's no word on where Michelle currently is, but from the sounds of her Twitter feed she's having fun!
Mich tweeted last night: "Just polished off 4 Oreo cookies and a cold glass of milk! #twist #dunk #lick #eat & I don't regret it 1 bit!"
When Mark's brother Josh joked that she obviously felt guilty enough to tweet about it, she replied: "Ok, after the 3rd I thought no that's enough but greed took over now I feel a lil sick! AND they're DOUBLE STUFF #sugarrush."
Mark and Michelle became engaged while on holiday in Dubai last year and are planning a wedding for next summer. They'll soon be taking the next step in their relationship when they finalise a house purchase in Essex.
After leaving her role as Tina McIntyre on Coronation Street, gorgeous Michelle is planning a move to Essex to live with Mark. They currently split their time between Essex and Manchester.
"We have virtually bought a house now," said Mark in February. "It's going through at the moment. It feels good. It's another step in life and exciting."
