Anyone else excited about Kourtney Kardashian and Travis Barker’s inevitable Halloween couples costume? Since they won’t stop talking about how they “want each other’s skulls,” I’m gonna assume these two are going as vampires/cannibals on October 31—but they’ve already debuted one Halloween costume a few days early: Nancy and Sid.

Travis walked the red carpet dressed as Sid at the NoCap x Travis Barker House of Horrors concert on October 19 in Malibu and truly went all out with spiked black hair, an “I’m a Mess” button, and a leather jacket. He even covered up his face tattoos to look more authentically Sid:

Here’s the look he was recreating, FYI:

Meanwhile, Kourtney didn’t walk the red carpet with Travis, but thanks to everyone’s fave Kravis fan account @KravisDaily, we know she was there dressed as Nancy. You can see their exclusive photo of her from the event over this way!

As a reminder, Kourtney and Travis got engaged this past weekend and they’ve since shared a bunch of photos to Instagram—including the moment Travis got down on one knee and Kourtney’s reaction to his proposal:

AND an up-close shot of Kourtney’s massive diamond ring:

A source tells E! News that Kourtney “had no idea” Travis was going to propose on the day of, saying, “They had just got back from NYC and decided to do a day trip to Montecito. Kourtney thought it was going to be a casual day, as they always go to Rosewood, and she was totally thrown off.” But of course once the proposal went down, “it was super emotional and sentimental. Kourtney was so happy and was definitely emotional. She teared up and couldn’t stop saying ‘I love you.’”
