A good ex-husband will respect your space, treat you civilly in front of the kids and warn you when his penis will pop up all over the internet. It's called being a grown-up.

In August, photos surfaced of Orlando Bloom and Katy Perry on vacation in Italy doing things couples do — kissing by the beach, hugging along the coast and, in Bloom's case, going paddle-boarding completely naked. Paps caught it all, and Miranda Kerr, Bloom's ex-wife, told Australian radio personalities Kylie and Jackie O that he at least had the decency to give her a heads up. What a guy.

Bloom and Kerr, married from 2010 to 2013, share a five-year-old son named Flynn.

"Oh my God, he text me and was like ‘um, I'm really embarrassed, some photos are coming out, just thought I should let you know,'" Kerr recalled. "And I was like, hmm, right, what were you thinking? Seriously?"

Press picked up on the fact that Perry and Bloom were dating around March, when they were seen together at a rally for Democratic Presidential nominee Hillary Clinton — an important but decidedly less-nude event. A source told People in August that Bloom and Perry are allegedly headed toward an engagement, and that Bloom is eager to have kids with Perry.

Kerr got engaged to Snapchat CEO Evan Spiegel in July after two years of dating. Her ring could probably kill someone if she gesticulated wildly.
