That awkward moment when you bump into your ex-girlfriend's sister's boyfriend? Yep, Scott Disick knows all about that.

There’s certain people you REALLY don’t want to see when you’re going through a break-up. We’re pretty sure that your ex-girlfriend’s-little-sister’s-boyfriend is quite high on that list. Unfortunately for Kourtney Kardashian‘s ex Scott Disick, that’s exactly who he bumped into while going about his business in LA.

And good Lord, it was AWKS.

Scott’s face as Tyga approached him looked very much like the expression of a man who knows he just has to grin and bear it through some uncomfortable small talk for the sake of keeping the peace. Kylie Jenner‘s rumoured¬†boyfriend Tyga, on the other hand, seemed to be enjoying making Kourtney’s ex squirm.

At one point, he clapped him on the shoulder as Scott looked at him, stony-faced. As friends of both men looked on, Scott seemed to get agitated, raising his hands as if to protest what Tyga was telling him.

And just what WAS he saying? Could he have been imparting romantic advice, gloating about his alleged relationship with Kylie, or telling Scott just how great Kourtney was getting on without him? Or was he just telling a really terrible joke?

Neither man has made any reference to the meeting on social media, so it seems we’ll be left guessing for now.

But in case you needed more evidence that it was really, really awkward, take a look at this guy.

Scott’s companion’s expression looks like one of a man who isn’t sure he likes what he’s witnessing.

Despite things looking heated, Scott and Tyga managed to end their meeting with a handshake and a hug. Which is probably a good idea – nobody wants to incur the wrath of the Kardashian girls!
