A few weeks after Selena Gomez's new single Bad Liar first penetrated our earholes the music video's finally here; and eagle-eyed fans have spotted one of her BFFs hiding in there.
They go way back and even appeared in the badass Bad Blood vid together, so it makes sense that Taylor Swift's featured in Selena's new one in the form of an Easter egg-type thing.
It's a bit blink-and-you'll-miss-it, but she's in there. SNEAKY.
If you check the posters on Selena's walls in the bedroom scene, you'll spot Taylor on two of 'em; one of them being a spoof Charlie's Angels-type affair.
Chatting to Seventeen a while back, Selena properly gushed over TayTay saying: "Every single problem I ever have is healable by Taylor Swift.
"If I ever I have an issue, Taylor has gone through it, because she's older than me, and she gives the most thought-out answers. And what I love about Taylor is that she does believe in the whole love story and Prince Charming and soul mates. Because of her, I haven't lost faith. We literally talk every day."
Watch the full video here, if you fancy. It's a bit brilliant.
Right, now where's our invite to join the squad?
