During Wednesday night's episode, viewers saw Mario enjoy a little flirt with Chloe in the gym, shortly after Mario admitted to the boys that he and girlfriend Emma McVey were going through a "really bad phase".
Now speaking in a video on the official TOWIE website, Mario said: "I don't know why I got shy with Chloe Lewis the other day. I don't know if it's because obviously I've got a girlfriend so I felt a little bit guilty. I didn't want to be too flirtatious, so I didn't really know what to say. I was a bit out of my comfort zone.
"And I'm not really the sort of person to approach girls," he continued. "I'm actually quite shy in general, even though my bravado suggests differently. I've got to work on my mojo!"
Despite the little flirt, Mario said he and Emma are still very much together.
He added: "I'm 27 years of age, I do have a girlfriend. Whether it's rocky or not I respect my situation more than to let other people put things into my head."
Mario's admission that he and Emma are going through a difficult patch follows on from her Twitter comments last week, where she hit out at her Italian tailor boyfriend after Ferne McCann tried to set him up with Chloe.
