There have been consistent rumours about Gethin’s sexuality but I’m not sure whether they’re based on anything other than his tendency to flirt clumsily with goodlooking men.
(I can’t work out how to link gifs but suggest you google “Gethin Jones Matt di Angelo gif”).
He was briefly engaged to KJ though but they split and she’s now married to an American with a young child.
I did think that Ian’s wilful manoeuvring of Gethin into the most ludicrous and homoerotic moves possible was hilarious as a one-off but did verge a bit on the assumption that being gay is inherently funny which would be dodgy as an ongoing running joke, so safest to move back to Zoe. I’d quite like to see him doing Wednesday Warm Up with Erin though.
