It's the Kardashian clan's worst nightmare!

Tyga and Blac Chyna both showed up at the event last night in Beverly Hills, and Lamar Odom was there too! They should have snapped a selfie and sent it to Kris Jenner. While it had the potential to be a very awkward scene, the former stripper actually told reporters that she and her rapper ex are "good" and trying to co-parent son King.

We wouldn't put it past BC to try and make a move on Lammy, just to create even more drama for the K family. The former Laker would probably fall for it, too, because he hasn't been dating anyone seriously since his split from Khloe Kardashian.

It's a little surprising that Rob Kardashian's ex-fiancee is so cool with T-Raww, considering the recent interview he just gave, in which he claims he warned the sock designer about his baby mama.

"I told him what the play was. I told him, like, what he was gonna deal with, you know what I’m saying? When I was with [Kylie], I told him like, 'Bro I was just with her for three, four years. This is what you’re about to deal with,’” he told The Breakfast Club. "She just Chyna. She just got a different mentality. She really is a good person — you feel me — at heart, but she’s been through a lot in her life, and she didn’t have people to help guide her and stuff in her life," he continued.

"I mean when we was together, I held her down, but after we broke up, she was doing her own thing and hustling. It’s not the fact of what type of girl she was. I knew a [guy] like him wasn’t going to be able to handle a girl like that. He’s coming from a whole different world. He don’t know how she moves and how she thinks. When you’re in love and when you don’t care what nobody else thinks, love blinds you," he added.

They make Scott Disick look like a dream in-law!
