Ed Sheeran and One Direction are some of the biggest stars on the planet right now, but just because they're pop stars doesn't mean they party like rock stars. In fact, they actually hang out like the cutest senior citizens ever.

"Whenever I hang out with them, they are very relaxed," Sheeran revealed. "A couple came to stay at my house over Christmas. When Niall was there we played Monopoly, and when Harry was there we watched 'One Day' because he insisted on seeing it."

(Okay seriously, how adorable is this visual right now?)

"I didn't know what it was but I was made to watch it," Sheeran laughed of the sappy flick. "Harry fast-forwarded it to the end, showed me the bike bit, and said that's what happens and then we watched it. The last couple of times we hung out, we did the least rock n' roll things."

Sheeran admitted there's a reason for their good behavior -- aside from just not being jerks.

"Nobody goes round smashing TVs any more. Everyone in music, bar a couple of people, is really polite now," Sheeran explained. "The reason is people have to like you to buy your record. You can't just go out there and be an idiot." Amen to that!
