I watched the video and it wasn't shade. Totally out of context.
It is true what he said. Most of the time it is difficult for the contestants to sing a Britney song. They often totally butcher them.

Digging a deeper grave for himself I see.

he's so annoying

mess

that isn't even a shade....

Welp, thank **** we don't have to worry about him being on B9, maybe God does exist

Oop

I didn't know Rita Ora had a british accent

Well at least Everytime is much better than the trash he produced for Britney Jean

Even though he's shading her, hopefully this will mean he will stay far away from her music. I always get the vibe that he collaborates with others just to advance his own solo career.

When you look like a cartoon character, you have no room to talk.

I really doubt he meant it in a malicious way, he was most likely referring to her unique vocal style.

Go & watch the video. He's just praising Britney's unique voice even though I low-key wished he shaded her.

don't think that was shade.

he's still garbage tho

you do realize that he praised her around the release of Britney Jean, hes probably pissed cause he got rejected from B9

Oh Will... x|

Gays thinking everything is shade as per.

This is like the thing Simon Cowell said about Adele/Gaga. Their music is so unique to themselves that its near impossible to be as good as the original.
