Lewis said his life was "complete" after bumping into Entourage star Jeremy at the ITV summer party on Thursday (17 July).
Reality star Lewis couldn't contain his excitement as he posed for a quick photo with the star.
Referring to Jeremy's Entourage character, Lewis said: "Met Ari Gold. Life Complete."
While an Entourage film is currently in post-production, more recently, viewers would have seen Jeremy as the star of ITV's lavish period drama, Mr Selfridge.
Jeremy plays charismatic American entrepreneur Harry Gordon Selfridge, and filming for the third series is currently underway.
All in all, it seemed like it was a pretty good night for Lewis, who tweeted this afternoon (18 July): "Thank you @ITV summer party, coolest party I've ever been too."
Lewis was joined at the summer bash by his co-stars Dan Osborne, Fran Parman, Gemma Collins and Ferne McCann with boyfriend Charlie Sims.
Also in attendance was Danielle Armstrong and Georgia Kousoulou, who managed to grab a photo with Take Me Out presenter Paddy McGuinness and Celebrity Juice host Leigh Francis - aka Keith Lemon!
