WATCH: Seth Rogen Talks Who Has a Bigger Penis Between Orlando Bloom and Justin Bieber

Not even celebs can resist the temptation of a good old fashioned penis pic. Last week when paparazzi photographed Justin Bieber and Orlando Bloom separately vacationing in the nude, everyone got a look at their respective penises, including Seth Rogen.

Last night during an appearance on Watch What Happens Live, host, Andy Cohen couldn’t help but ask Rogen what he thought about the penis pics,  “Who would you say—as a straight guy—had the nicer penis of the two?”

“I’ve seen Justin’s before, so maybe I was just like, you know, ‘I’ve been there, done that,’ a little bit. And it’s a wonderful one!” he said, before later explaining that he’s seen another paparazzi pic of Bieber’s junk and not irl.

“But Orlando’s, I was really happy with,” he joked. “Good for him! He’s in great shape overall. So I thought, honestly, Orlando’s probably a bigger guy, and proportionally, his penis looked to scale, which makes me think overall it’s probably bigger.”

But Bloom’s penis isn’t his only body part Rogen was impressed with. When Cohen declared, “Dick aside, Orlando has got a can on him,” Rogen enthusiastically agreed, “Oh, yeah, he has a bubble butt!”
