In a new interview, the amateur boxer admits he didn't want his steamy scenes with the 23-year-old R&B star to come to an end.
Speaking to UK newspaper the Evening Standard, he said: 'You've just got to get into it.
'It took about three-and-a-half days to film. I loved it. I didn't want it to end. Not just because it was 'a certain person's' video, but just because I love being on set.'
O'Shaughnessy also claimed that he “wasn't star-struck” by the Rude Boy singer because she was so easy to get on with.
He said: 'I wasn't star-struck at all. She's just such a nice girl. It's not like just because she's achieved so much that she thinks her s*** don't stink.
'She's such a humble, down-to-earth girl and that made it even better for me just because I didn't feel intimidated or anything. We just got along. We were just like mates.'
He also revealed that appearing in the video has fuelled his desire to make it as an actor.
He said: 'I don't want to do anything like EastEnders, I want to do film, or proper gritty TV. I'd like to do something with Guy Ritchie. I'd like to be the villain, but the villain never wins. This time the villain would have to win!'
