Justin Bieber may have implied that his video for “All That Matters” is about ex-girlfriend Selena Gomez, but she wasn’t the one kissing him in the video. That was 19-year-old Cailin Russo, and she’s ready to spill the deets on what it was like to kiss Justin — and if she think he’s still got feelings for Selena or not.

And despite Justin’s behavior as of late, he was actually pretty sweet to Cailin. “He was so nice to me and we were fully conversating the entire time,” she told Cosmopolitan in a recent interview. “We would even go into the tour bus in between sets and talk. He’d play me his some music, like the song with R. Kelly. It was fun.”

Now for the real question: is Justin Bieber a good kisser? We have to know.

“Yeah. Kissing him was nice — I got butterflies and still do to this day,” Cailin revealed. “After the shoot wrapped it felt so surreal. I even got a speeding ticket after the shoot because I was on such a high. I guess you could say I wouldn’t mind doing it again!”

And apparently, the whole kissing thing went so well that Justin and Cailin have stayed in touch, texting and even occasionally FaceTiming. But Cailin’s not looking for anything serious — she’s already got a boyfriend.

Although, now that you mention it, she is a little hurt by the diss Selena may or may not have thrown her way on Instagram.

I'm sure there might be bitterness, but I was just doing my job,” Cailin said. “She posted a picture on Instagram that said, ‘I thought he only liked the Latina category. Smh... #nomakeup #hatewhengirlssaythat.’ It was clearly directed at him with me in the video, but like I said I was just doing my job.”
