Rylan Clark really does know how to wind up Gary Bore-low *ahem* Barlow, doesn't he?
Can somone go check on Gary? We think we just heard him explode. Copyright: [rex]
This week, all the X Factor contestants were treated to a master class with none other than Gary Barlow's old band mate, Mr Robbie Williams!
Yep, that meant it really was a case of when Robbie met Rylan.

And we know that Robbie is a Rylan fan after he tweeted his support last weekend.
So we actually can't wait to see what the pair got up to on this week's show, we wonder if they sung Back for Good and Rylan filled in for Gary?

But in all seriousness, Robbie and Rylan's love in did spark one worry for us: that Gary Barlow might actually finally implode with fury.
However, if you want to ask Rylan about what he and Robbie really got up to, or any of the boys as it happens, then you can!
At about 4pm today omg! will be hosting a Twitter chat with all the boys (plus Kye!) where they will try their best to answer all your questions.
All you need to do is tweet @yahooomguk with #omgxf and your question!
Plus, we will be bringing you all the latest goss from the rehearsals.
