How the Kardashian family shaded Tristan Thompson at Kylie's 21st birthday

Well, this is awkward.

There's no way that you could have been online over the weekend and NOT seen Kylie Jenner's larger-than-life birthday celebrations. Kylie had an all-pink venue and a whopping three outfit changes to ring in the big 2-1.

While we may have been obsessing over everything the Kardashian-Jenner fam wore, there was a significant slice of shade dished at the party that kinda went unnoticed…

Enter Tristan Thompson and a whole host of awkwardness.

During the festivities, footage was captured of a massive birthday mural made for Kylie, featuring her whole family, their plus-ones and even some deceased Kardashian-Jenner members.

The mural included Robert Kardashian Snr, Kanye West, Scott Disick and even Kendall's relatively new boyfriend, Ben Simmons.

However, Khloé Kardashian's boyfriend and baby daddy, Tristan Thompson, was missing from the line-up — and from the whole party, supposedly because he was coaching a basketball camp in Toronto, or perhaps he wasn't invited by the birthday girl??

While the lack of feature in the mural was one bucket-load of shade from Kylie, Khloé herself also managed to diss her other half with her choice of cup at the party.

Kylie Jenner opted for a colour-coded cup situation at the 21st, where you had to drink from the cup that best described your relationship status: Taken, Single AF and It's Complicated.

Later on in the night, Khloé was caught in an Instagram Story clutching a green cup — telling the whole wide world that she defines her relationship with Tristan as 'complicated'.

This sure isn't a great omen for Khloé and Tristan's future…
