Mark met the legendary Hollywood actor while filming the latest episode of Alan Carr: Chatty Man and couldn't wait to get a photo with him.
After grabbing SLJ on set, the pair posed for the snap and they even managed to get photobombed by Caroline Flack. Good work, Caz!
Sharing it on Twitter, Mark gushed to his fans: "It had to be done. When he was talking I closed my eyes and thought I was watching Coach Carter. LEGEND!! #1ofthebest #SLJ."
Mark and Caroline will appear on tomorrow night's episode of Chatty Man to talk all things Strictly Come Dancing, as they are both competing in these year's show.
The pair have both got off to a good start, with Caroline finishing in third place after the first episode. Mark, meanwhile, ranked in at 8th on the leaderboard, which isn't bad considering there are 15 celebrities taking part!
Saturdays' star Frankie Bridge is currently the one to watch, as she and her professional partner Kevin Clifton finished in first place, but there's still a long way to go and everything can change!
