The Essex favourite was sitting in a cafe with co-stars including Bobby Cole Norris on last night's episode of the ITVBe show, when they spied Mario chatting on the phone outside the window.
Well, they spied his bum anyway!
"He has a cracking bum on him," noted Bobby.
Jess agreed, adding: "I was just going to say… Look at those trousers. Tight little ass! He's been doing his squats!"
It was a bit of a random exchange in the scene but it did make us laugh!
And Jess and Bobby aren't alone in their gushings about Mario's rear end. There were plenty of complimentary comments on Twitter during the show, including: "Best bum in TOWIE."
We wonder what Mario's model girlfriend Emma McVey has to say...
