So who is this girl in Justin Bieber's new video that Selena was definitely throwing shade at? Cailin Russo, is her name and sources say that her and Bieber had some "pretty intense" chemistry. Cailin is a 19-year old model from San Diego and she is hot! Sorry Selena, you will always be our fav don't worry!

We love to talk about Justin Bieber and what he is up to. Surprisingly this news didn't make us roll our eyes and shake our heads too much. Justin Bieber has a new gal pal and wait for it...she isn't a Brazilian prostitute (yayyy). Bieber had recently posted a picture of a blonde beauty, Cailin Russo, kissing his cheeck with the hashtag #allthatmattersmusicvideo on his Instagram. Cailin then shared the same picture saying, "Guess the cats out of the bag", confirming that yes, she will be starring as Justin's girl in his new music video for "All that Matters". You know who didn't take this news very well? Ex-girlfriend Selena Gomez. Even though Selena seems to be over Justin and has not thrown any "subliminals" at him for any of his other escapades, she felt the need to do it now. Selena posted a selfie on Instagram looking gorgeous with no make-up and added the caption "I thought he only liked the Latina category" BAM! Maybe Selena predicts Cailin can be more than just a "one nighter" for Justin? Oh oh.

The music video is very sensual and Cailin is all over Justin, who along with his team chose her out of a bunch of girls who submitted a casting video. That "tell all" source tells E! News that Russo "was really surprised how super easy it was to work with him". Even the director of the video, Colin Tilley was "in love with both of them", the source even saying that they got really close during the video confirming that "they keep in touch". Trust me, you can definitely tell, as all of the teasing and rubbing in the video ends up in a passionate slow kiss as Russo is straddled on Justin's lap...very steamy. It's a good ballad with a good video, the only part that was super weird was when Justin is shirtless grabbing his...you know, attempting to pull a sexified Michael Jackson move? It's super awkward.

Can this be a new couple alert? Or will Justin always have a soft spot for the Latinas? Guess we will have to wait and see as the endless book of Justin Bieber's shirtless and wangster adventures continue.
