Wayne and Chloe sent ripples through the showbiz circuit with the apparent news of their engagement, surprising their own co-stars.
It was a twist of fate when their paths crossed on the latest series of Celebs Go Dating where they were on a quest to find true love.
However, Celebs Go Dating star Tom Read Wilson waded into the drama on Thursday as he gave his verdict on the pair's so-called happy news.

The reality star receptionist cast a shadow of doubt on wild engagement rumours which hit the showbiz circuit on Wednesday night.
He told Capital FM 's Roman Kemp: "I have to say I’m not sure it’s real, when I was speaking to your divine producer this morning that was the first I’d heard of it!
"Honestly you could have knocked me down with a feather, I could not be more surprised. I would have thought Joey [Essex] and I before that. I really would."

Cheeky Wayne added fuel to the fire of the engagement news when he affectionately called Chloe his "wifey" beneath her latest Instagram post.
He wrote: "Looking good wifey."
Cameras were rolling when the pair grew close on Celebs Go Dating.
