Model Xenia Deli, who stars alongside Justin Bieber in the new music video for his new single 'What Do You Mean', has revealed that he is a great kisser. 

The beauty told Harper's Bazaar magazine that filming the steamy video was a lot of fun and he made her feel very comfortable on set, which was good as they had to get quite close fairly quickly: "Imagine that, if we were going into a corner and practicing, but no. We were on set, and we had been talking for a little bit, and we knew that this was our job, so we just did it."

"The first scene we filmed was when I was lying on the bed, and he was singing - we did that for a pretty long time. We had been talking in between shots and getting to know each other better, so it wasn't that weird when it came time to make out. But we had to make out a lot. We were trying it from different angles a lot of times."

She went onto add that some of Bieber's fans have responded negatively to her involvement in the music video and she was surprised to see mean comments shared online about her: "There have been so many negative comments. I wasn't expecting this reaction - I thought everyone would be excited! I can't do anything about it though. It's not about me. Whatever they do, it doesn't say anything about me, it says more about them."

"But I just want to say, I didn't do anything wrong, I was just doing my job. I'm not taking Justin away from his fans. I'm so sensitive to what people think about me, so I just stopped reading the comments."
