Katy Perry’s been stirring up dating buzz with Justin Trudeau — and now Orlando’s jumping in on the fun, praising a joke about getting his own political situationship.

You’ve gotta see it — Orlando dropped a comment under The Onion’s recent hilarious headline: “Orlando Bloom Spotted At Dinner With Angela Merkel” … which accompanied a wild A.I.-generated pic of him and the former German Chancellor.

The fake pic showed Orlando and Angela sharing a romantic candlelit dinner, with a bogus source claiming he “couldn’t keep his eyes off Angela.” Orlando’s response? A cheeky “👏👏👏!”

It’s a hilarious jab — but LBR, things between his ex Katy and former Canadian PM Trudeau seem to be heating up … even if sources keep insisting they’re just friends.

As you know, we caught Katy and Justin grabbing dinner earlier this week — and he even showed up to her “Lifetimes” tour stop on Wednesday!
