Justin Bieber is seeing red and why? Well, the infamous on-and-off lovebirds - Bieber and Selena Gomez - are feuding again.

Seems Selena Gomez (21) has rattled the possessive side of the "Baby" hitmaker (20) by allegedly flirting with Orlando Bloom in the open. Seriously.

Both Justin and Selena are notoriously jealous and insecured and can't stand their other halves talking to anybody else, let alone flirting. Bieber is so used to his lady-love's affections that he hates her interacting her with anybody else.

So when Gomez got pally with Bloom during the We Day California conference held on March 26, it simply was like a “slap on the face” for Biebs. To add insult to the injury, pictures of Selena posing with Bloom and Seth Rogen — on of the stern anti-Bieber, were splashed across the internet, firing jealous accusations from the pop brat.
