However, it is Taylor Swift's reaction to it that has set everyone's tongues wagging.
The '22' singer couldn't help but hide her distaste as the on-off couple shared a peck on the cheek backstage at the ceremony.
After clocking the pair sharing a moment, Taylor smiled at the couple, before turning round to her entourage and making a vomit face.
Looks like someone isn't a fan of her BFF's boyfriend. Awkward.
But we doubt she's really that bothered after picking up eight, yes eight, gongs at last night's awards.
