The Leave Right Now singer said he has still not heard from the BBC or the producers of the game show show — in which a celebrity panel must guess the true owner of a home — over his claims the remark was homophobic and offensive.
Young, 42, shared an angry post on his Instagram stories about the latest episode of This Is My House in which Made In Chelsea star Matthews, 32, asked who "the least gay person is?" while trying to guess the home owner.

Young wrote: "Asking 'who is the least gay' on This Is My House I find completely offensive. What does 'least gay' mean? Most 'masculine', least 'effeminate'?
"For f***s sake BBC don't you realise it is completely reaffirming offensive and shaming stereotypes? I'm gay, take it up the b** and like football and cars. Might blow your mind... Spencer Matthews."
He later revealed he had been Matthews had been in touch to say sorry.
Young wrote: "Spencer Matthews has had the maturity and respect to respond in a very understanding way and I completely appreciate it. Thank you sir."
But the Pop Idol winner revealed: "No reply from BBC, makers of the show This Is My House, BBC iPlayer or @BBC.
"Or perhaps some sort of understanding and sense of being educated from privileged reality show person (which I am aware I am as well)."
Yahoo has contacted the BBC for comment.
This Is My House, presented by Stacey Dooley, sees four contestants show off one home to a panel of guest celebrities. If they can convince the panel they are the true owner they win £1,000.
The singer wrote in his book To Be A Gay Man: “BBC Radio 1 breakfast show DJ Chris Moyles decided to embark on a rampage of homophobia against me – on my birthday no less. It was something that left me aghast, especially as he and I were on friendly terms.”
Moyles spoofed a selection of Young’s hit singles, changing the lyrics to mock his sexuality.
In his version of Young’s No 1 single Leave Right Now, Moyles sang: “Oooh Will Young here, mmmm. I'm here, it's Will's birthday and as the years go by I get more very gay.
“When you saw me years ago you didn't know, but now I'm the gayest fella you probably know. Mmm I like to wear a silly hat, I get camper by the hour, oh would you look at the muck in here. I'm Will Young and I'm gay.”
