Justin Bieber is more agitated with the thought that Selena is bisexual and dating Cara Delevigne than the fact that she's seeing Italian businessman Tommy Chiabra. At least, that is what his recent actions conveyed.

The UK's Daily Star reports that the Canadian singer, who is flirting with almost all the models in the planet, is making a fuss out the "Come and Get It" singer's new budding friendship with Cara DeLevigne. Cara is a bisexual British model who recently dated Michelle Rodriguez before they called it quits due to work commitments.

The newspaper claimed that Justin was even personally calling Cara up to know the exact details of their friendship. In fact, he called more than once. The calls were made by an obviously drunk Justin Bieber too.

"Justin has called Cara on more than one occasion, wanting to know what's going on," an insider tells the newspaper. "It's been clear that he's had a drink beforehand, too."

Justin should not really worry. Cara may have a bried liaison with Michelle Rodriguez, which cemented her identity as a bisexual, but this does not mean she has a thing for Selena Gomez or vice versa.

Sources close to the model claimed that Cara and Selena's relationship is strictly platonic.

"She's just having fun with a new pal," one source argued.

Considering Cara was the person lucky enough to share a fun-filled week with Selena for the former Disney star's 22nd birthday, speculations of them being more than just friends naturally came out. Too bad Justin actually put color into this relationship, especially since he has no right to. Also, if there's anyone Justin should be jealous of, then it must be Tommy Chiabra, considering Selena really has a crush on him. Justin may be relieved to know that Tommy is the one holding back on this possible relationship, but for how long?

"Selena definitely has a puppy dog crush on him that is only intensifying because he isn't taking the bait." Hollywood Life reports.

"He knows he has her but is currently going the friend route even with all the obvious flirting that is going on."

Tommy and Selena celebrated her birthday jet skiing, cuddling, and showing a lot of PDA too, Hollywood Life reports.
