Selena Gomez 'jealous' of Justin Bieber's 'All That Matters' music video girl? Cailin Russo claims ex-girlfriend dissed her on Instagram with 'I thought he only liked Latina category' jab

Aspiring model Cailin Russo is the lucky girl that stars in Justin Bieber's new music video, "All that Matters" -

Things get pretty hot-and-heavy in the sulty clip. Is Bieber's ex-girlfriend Selena Gomez jealous?

In a recent interview with Cosmopolitan magazine, Russo discussed working with the Biebs. The stunning model also insisted that Gomez dissed her in an Instagram post while she was working "up close and personal" with the songstress' "Believe" ex on-set. According to Russo, Gomez "posted a picture on Instagram that said, 'I thought he only liked the Latina category. Smh... #nomakeup #hatewhengirlssaythat.'"

Russo explains, "It was clearly directed at him with me in the video, but... I was just doing my job."

The American Apparal beauty thinks that it's "ridiculous" some fans continue comparing her to the "Spring Breakers" starlet - "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 said.

Bieber and Russo are NOT dating and they were never romantically involved... but they do keep in-touch through FaceTime.

Gomez's "harsh" Instagram post was later deleted. She has yet to comment on the matter.
