Kanye West‘s comments about supporting Diddy during his federal sex trafficking trial weren’t just empty words … ’cause he just showed up at court to support the embattled mogul.

Our cameras were rolling when Ye arrived at the federal courthouse in Manhattan … hopping out of a black car in an all-white outfit.

He shook hands with a couple people out front, then headed toward the security check-in, but, before he got to the door, he ran into Christian Combs — Diddy’s son — dapping him up on the way in.

We also got video of Kanye walking through the courthouse … going through the same security checks as everyone else — no star treatment for anyone at a federal courthouse.

Kanye was also greeted by a member of Diddy’s legal team — Xavier Donaldson — so, we’re pretty confident Diddy’s already aware of his presence, even if the two haven’t seen each other yet.

Ye’s reportedly sitting in the overflow area … watching the proceedings with his security and the rest of the normies in the building.

As you know … Kanye’s one of the few stars who has stood by Diddy despite the accusations against him — putting a phone call he had with Diddy from federal prison in Brooklyn on a song he released in March.
