At the Billboard Music Awards, Taylor Swift had a message for her critics: “Haters Gonna Hate.”

To mark her first performance of “22” on television, Swift wore a “Haters Gonna Hate” unicorn graphic tee. Though it is rooted in hip hop, Swift made the catchphrase her own — the words are in spelled out in glitter inside a rainbow-colored cloud that hovers over an image of the mythical creature.

Where did Swift get her cheeky T-shirt? 

The Junk Food tee sold out at Urban Outfitters before Swift’s performance, but a rep for the brand — which obviously understands that celebrity sightings equal increased sales for fashion labels — says there are plans to bring the style back soon. In the meantime, the men’s version is still available. For those with a more mature taste in message tees, PBS sells a Downton Abbey “Haters Gonna Hate” shirt featuring the villainous Thomas and O’Brien.

And speaking of haters, Swift could hardly hide her disgust when she spotted BFF Selena Gomez planting a kiss on Justin Bieber backstage, a moment that has been immortalized in GIF form.
