Justin Bieber's Vegan Diet Made Him A Jerk!

Say whaaaat??

Usher recently went vegan, as we previously mentioned, and he also got Justin Bieber to try it too.

The meatless, dairy-free and fish-free diet apparently turned the Biebz into a real jerk!

An insider said:

"His mood took a major nose dive — he was such a brat. Soon everyone was begging him to just eat a steak! Justin ordered a tofu steak and tempeh tacos from Real Food Daily in L.A. and was really grossed out. He made a big show of spitting out the food and making gagging noises."

Ha! We guess he didn't like it!

Seems kinda immature to make a big scene of it, though.

Selena Gomez even got tired of his jerkiness. The insider said:

"She had encouraged the health kick but [told] him to drop it. She said that being vegan turned Justin into a jerk."

Wow, it's amazing how much our food can affect our mood. Maybe it's because they're only one letter away from one another… LOLz!

We feel like he really didn't give it a chance and was just not interested in trying the diet.

Maybe Usher kinda forced it on him.

Go get yourself some In N Out, Biebz!
