Actor Michael Madsen has revealed what it was like punching Justin Bieber on the set of his new video for 'As Long As You Love Me'.
The Hollywood actor appears in the video for Bieber's latest single from hit album 'Believe' alongside rapper Big Sean.
Speaking to MTV News, Resevoir Dogs actor Madsen said that he might have enjoyed the more physical scenes in the video if he had not liked Bieber as much as he did.
"I didn't exactly enjoy slapping him around," he said. "Had he been a p****, had he been a brat, you know, I might have had fun with that. But he was actually, he was the opposite."
Adding: "He was very respectful, very respectful and decent to me," he admitted. "I think he wanted it to be well-done. I don't think he was blowing it off. I think that I've been around enough to know I can tell if somebody isn't really doing their job or taking what they do seriously.
"And I could tell from early on in the morning that he was. He wanted it to be right. He wanted it to be specific and had a good car, a '68 Charger.
"That's a pretty b****ing car, you know? I saw that damn thing parked in front of the house and I went 'Wow, I hope that's mine.' But they put me in a Rolls Royce; not too bad at all."
Meanwhile, it was revealed this week that Bieber is currently writing new songs for girlfriend Selena Gomez.
