WATCH: Justin Bieber, a 'good kisser'

The 25-year-old beauty starred alongside the 'Boyfriend' hitmaker for his latest music video 'What Do You Mean?' and has admitted that whilst she enjoyed kissing him, it was just her "job".

She joked: "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."

And after starring alongside the 21-year-old singer, Xenia has been on the receiving end of a lot of negative comments from his fans, something she is keen to avoid.

She told Harper's Bazaar magazine: "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."
