Orlando Bloom is the textbook definition of post-breakup hotness … because he’s looking absolutely jacked after calling off his engagement to Katy Perry … and giving an ex a look at what she’s missing out on.

Check out these photos of the “Pirates of the Caribbean” star shirtless at a beach in California … Orlando’s ripped and showing off his chiseled abs and pecs.

Katy’s been spotted hanging out with former Canadian prime minister Justin Trudeau up in Canada … so she may not be exactly thirsting after Orlando here.

Orlando joked about KP and JT last week, reacting to an Onion article … but he looks unbothered here … the guy is a total stud.
