Cailin Russo was actually very polite in her response to Selena Gomez's diss. The model and aspiring actress explained she understands Selena's reaction after seeing her ex all over a new girl.  Cailin tells Cosmo that she was simply doing the job she was hired for.

After seeing a photo that Justin posted on his Instagram with model Cailin Russo, Justin's girl in his new video "All That Matters", Selena decided to respond with a photo of her own. Even before the release of the steamy video Selena took to Instagram to post a makeup-less picture of her with the caption "I thought he only liked the Latina category. Smh..." When asked what she thought about the diss during a Cosmo magazine interview Cailin said "It was clearly directed at him with me in the video...but like I said I was just doing my job". "Selena is a superstar and I'm just a girl in a video. She's his ex, and I'm sure they still have feelings for each other". Nice response... in other words saying, I'm not competing against her and it's not like I could anyway.

The video vixen also revealed that she is taken, even if Justin was into her, is not like she could give in to his charm. " I had a boyfriend up until the video and the drop...we broke up for about a week after, but we're back together...for now". Doesn't really sound like a sure thing, seems like Cailin's boyfriend was feeling a bit insecure about the video himself. You cannot blame Selena and "the boyfriend" for being jealous, the video consists of a lot of rubbing, touching and ends in a passionate kiss...caliente! But everybody can relax now; Justin and Cailin are just co-workers...maybe. Oh teenage drama, isn't just so entertaining?
