This evening is the third episode of the revived series, which is being hosted by Paul O'Grady.
The new show has proved a hit since it returned to screens last month more than a decade after it was last on air, then hosted by Cilla Black on ITV.
To tie in with the London Pride festival over the weekend, tonight's show will feature a same sex dating round for the first time ever.
We'll meet single Celine Dion super-fan Alice who will be quizzing a trio of potential suitors Steph, Sarah and Jane.
But while the same sex line up is a first for the show, expect the usual cheesy chat up lines as Alice decides which of the trio she fancies a date before seeing them.
Host Paul O'Grady said of the show: "It’s 2017 – you’ve got to educate people. It’s no longer boy meets girl. It’s boy meets boy, girl meets girl, boy meets whoever, whatever floats your boat.
“You have to acknowledge that. You can’t just have same old, same old. I think it’s really brave of them to make this step, because the others wouldn’t.
“Imagine the BBC? It wouldn’t happen, it just wouldn’t happen.”
It's said to be the first of several LGBT episodes for the new series, which launched to over 2 million viewers last month.
Blind Date airs tonight at the later time of 8PM on Channel 5.
