One day after those widespread reports of a scuffle in Ibiza, the cheeky popstar uploaded an old image to Instagram showing Orlando rubbing his eye.
He didn't add a caption. Not that one was needed.
Justin's post went viral, gaining more than 500,000 favourites in ten hours – and plenty of comments ranging from "immature" to "hilarious!"
The most unlikely feud of the year began at an Ibiza night club on 30 July when it's claimed Justin and Orlando become embroiled in an altercation. Sources say a punch was thrown at one stage.
Neither Justin nor Orlando or their reps has directly spoken out.
There's been no word on what caused the alleged confrontation but rumours have suggested it could be to do with Justin's friendship with Orlando's ex-wife Miranda Kerr.
For her part, Miranda has been keeping mum. Although still active on social media, she's ignored the feud rumours and instead posted pictures of herself modelling and walking with her and Orlando's son Flynn.
Will we EVER know what exactly happened?!
