The former TOWIE star was snapped leaving the Riverside Studios in London on Wednesday night (25 September) after taping a guest appearance for the ITV2 panel show.
And didn't he look good for someone who's been suffering jet lag after three months of jetsetting around the globe?
(We're not surprised, though. Let's face it, he always looks good!)
Mark has been working on a new series for ITV2 called Wright Off The Beaten Track, which will see him meeting different communities and groups around the world and throwing them unique parties.
He'll have just one week to get to know the group and their ways before throwing them the perfect party. Pressure's on!
Mark arrived back in the UK earlier this week, and tweeted: "Finally back to my home routes. 3 months of filming my series in the bag & what fun it was. Just waiting now to tell you all when its on TV."
No doubt fiancée Michelle Keegan was glad to see him back!
The couple announced their engagement at the start of September, but it seemed like Mark almost immediately had to jet off for filming.
Aside from working on his new show, Mark can also be seen in Littlewoods' new autumn/winter 2013 campaign alongside Myleene Klass.
We'll definitely be tuning into his Celeb Juice episode. We can't wait to see how Keith Lemon reacts to the engagement news... we all remember last time Mark was on the show Keith wasn't too happy he'd taken Michelle Keegan off the market...
