Ariana Grande has taken to Twitter to respond to Ed Sheeran after he revealed that she made him laugh with a dirty joke at the Victoria's Secret Fashion Show last week.

Snaps of Sheeran's awkward facial expressions went viral after he performed at the lingerie catwalk show in London, with the Thinking Out Loud singer admitting that it was actually Ari and not those underwear-clad models who made him giggle.

[related]Ed 'fessed up to Elvis Duran: "Can I tell you why I was laughing? Basically there were all these big inflatable bouncy black balls that are bouncing around in the crowdon the finale bit.

"Ariana Grande comes up and stands up next to me and just looks at me and goes, 'I love big black balls'. In my head I was like, 'If she knows what that means then I love her, and if she doesn't know what that means, it's even better!"

After hearing about Ed's little confession, the Problem singer took to Twitter last night to call out Sheeran over his comments, writing: "@edsheeran my time with @elvisduran should be really interesting this week thanks to u m8."

The red-haired wonder then replied: "@ArianaGrande @elvisduran hel think it's as amazing as everyone else I'm sure, u kool, u kool (sic)."

The 21-year old brunette then replied: "bruh", to which Ed responded: "bruh bruh".

We're guessing they're 'kool' after all…
