Last month it seemed Karlie Kloss threw some serious shade at her (former?) best friend Taylor Swift with a very suspicious tweet.

That wasn’t enough to convince us their pair were on the outs – but a new development might be.

Karlie was seen leaving a sushi dinner in Los Angeles overnight with none other than Katy Perry, Taylor’s long-time nemesis.

TMZ snapped Karlie, Katy and some friends leaving the restaurant together, and we can’t decide if they look shocked by the paparazzi … surely they can’t be surprised?

Karlie and Taylor haven’t been seen in public together in years, although the Victoria’s Secret model did wish Taylor a happy birthday on Instagram last year.

Unless Katy and Taylor have resolved their feud and not bothered to tell anyone, there’s no way Karlie could still be friends with Taylor and hanging with Katy, too.

Looks like there’s some Bad Blood going on here.
