Since they've been on our tellyboxes for the best part of four months, we like to think we know The X Factor winners Rak-Su pretty well. We follow 'em on Snapchat, can reel off all their surnames (Myles Stephenson, Jamaal Shurland, Mustafa Rahimtulla and Ashley Fongho, if you want to test us) and have streamed Dimelo 67 times already today.
One thing you might've been wondering for a while, though, is what the heck Rak-Su actually means.
Judge Sharon Osbourne obviously struggled with it earlier in the series, when she called the boys 'Katsu' in the first of the live shows, but now we can finally tell you the story behind their oh-so-unusual name.
On the lads' official site, they explain: 'The name Rak-Su comes from the phrase "Tracks vs Suits" meaning 'Music & fun vs Adult Life''; adding 'the aim is genuinely just to keep making more music, and spread more vibes.'
So there you go.
This all comes after the boys admitted they've basically got an album ready to go when Simon Cowell and the Syco lot give them the green light. Ahead of winning the show last week, Ashley told us: "I mean, we’ve got so many songs. Most of them are rubbish! Of the good ones?
"Obviously, our favourite ones we’ve used during the show. There are some others as well that we’ve been writing during the show that haven’t matched the themes, so we haven’t been able to use them.
"But yeah, I think we’re quite excited about the prospect of making an album, because we’ve got a lot of stuff ready to go."

Now let's look at loads of fit pics of Myles, shall we? Why? Oh, just because.
