Hey, Katie Couric, mind if we borrow your time machine? On Wednesday night, the 61-year-old journalist stepped out for Halloween rocking her finest Ariana Grande-inspired look, and um, I'll have what she's having. Thanks to her oversize sweatshirt, thigh-high boots, and long extensions, we almost didn't recognise her.

"Hey @arianagrande 🎃☠️👻 #godisawoman (changed hashtag after being chastised by a 22 year old Ariana fangirl I happened to give birth to) And yes, I know this is disturbing," she wrote. We're not quite sure what her 22-year-old daughter Caroline had to say about the costume, but what we do know is that it's far from disturbing.

Her photo inspired some double takes, with one person writing, "You look about 25!!! 🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻." Another added, "LOL I totally thought it was Ariana at first glance!" Read on to see Katie's Ariana Grande Halloween costume, and then see how Kourtney Kardashian also channelled the singer for Halloween.
