This town isn't big enough!

Caitlyn Jenner and her ex Kris got quite the surprise last night when they both showed up for dinner at Nobu in Malibu. Awkward! The two have a pretty longstanding beef going at this point, so we'd be shocked if they actually acknowledged each other inside the restaurant.

The momager recently slammed the transgender star for taking credit for the idea to shoot Keeping Up with the Kardashians. "It's so absurd. I'm not sure what the motivation was for her to say something like that. Maybe somebody should remind her that it's called Keeping Up With the Kardashians," she told The Hollywood Reporter.

The once amicable former spouses have been at war since the I Am Cait star released her memoir Secrets of my Life, and things haven't gotten any better with time. The whole K clan, minus maybe Kylie and Kendall, have little to no contact with the Olympian anymore, and that's got to make chance encounters pretty uncomfortable!
