Justin Bieber makes Selena Gomez jealous with Cailin Russo kiss in 'All That Matters' music video

Justin Bieber caused something of a stir with his new music video for "All That Matters." Released Dec. 2, the video already has well over 8 million views and has gotten fans in a tizzy over his shared kiss with model Cailin Russo.

But apparently fans aren't the only ones upset. His ex, Selena Gomez, posted an Instagram photo that some are interpreting as being a slight against Russo.

"I thought he only liked the Latina category. Smh... #nomakeup #hatewhengirlssaythat," she writes as the caption for the makeup-free selfie that has since been deleted. For the record, Russo is a Caucasian blonde.

The image seems to have brought Gomez enough backlash that she decided to delete it. One report claims she even denied the jibe at her ex before removing the image. While Gomez might act like she's above it, Russo isn't buying that the message wasn't directed at her and Bieber -- and she doesn't think Gomez has anything to worry about.

"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," Russo tells Cosmopolitan. "I'm sure there might be bitterness, but I was just doing my job. 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."

Russo -- who sometimes Facetimes with Bieber still -- also confirms what many Beliebers have been dying to know: he's a good kisser.

"Kissing him was nice -- I got butterflies and I do still to this day. 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," she says. Don't worry ladies; she's in a relationship.

Do you think Gomez was actually jealous?
