Canadian pop star Justin Bieber is reportedly spending time with Spanish model Yovanna Ventura to upset former girlfriend Selena Gomez.

The 20-year-old Baby singer sparked dating rumours after he was photographed with his hand on Ventura's thigh as they rode in a rickshaw through Venice Beach, California.

Bieber also posted an image to his Instagram, in which he seen wrapping his arm around the 18-year-old.

"Venice beach with my friend yovanna," he captioned the picture.

"Justin is just trying to make Selena jealous by hanging out with Yovanna," a source told Hollywood Life. "He knew it would get to her if he posted a pic with Kylie too. He's just acting like a jerk because Selena majorly deflated his ego when they broke up. She told him she wanted nothing more to do with the song they were working on and he just flipped and said she was overreacting."

The website also claims that Gomez "caught him flirting back and forth with Kylie [Jenner], she clearly doesn't want to have anything to do with him. And that's driving Justin mad".

"He said she was being paranoid about his supposed hook up with Kylie," the source added. "Selena just blew him off big time and now he's trying to play big shot!"

This news comes after reports emerged that Gomez unfollowed As Long As You Love Me singer and the Jenner sisters on Instagram after she discovered Kylie sent racy images of herself to Bieber.

"Kylie sent sexy pics of herself to Justin and that's what started the fight. Selena saw the pictures on Justin's phone and she freaked out and left immediately," a source close to Bieber told Hollywood Life.
