The 35-year-old actor is unsure why people think he is so good looking, but is grateful he has attractive parents.

Asked why he is so attractive, he said: "I don't know. I wish i could come up with something funny for this answer. My mom is beautiful and my dad doesn't suck either."

The 22 Jump Street actor was recently disappointed not to complete an expedition in Iceland because of the weather conditions - but he was fascinated by the fact it was so cold, his poop froze.

He said: "I just went to Iceland and tried to do a small expedition across the glacier and we didn't make it. We had to be emergency evacuated as there was a white out blizzard which I got to take a poop in. It actually freezes before it hits the ground."
