Veganism Turned Justin Bieber into a 'Brat'

At the suggestion of his mentor Usher, Justin Bieber reportedly tried his hand at veganism to very unsuccessful results. 

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

Apparently even Bieber's girlfriend Selena Gomez asked him to continue eating meat again. She reportedly encouraged the diet switch at first, but then urged him to start eating meat again because he was acting like a "jerk."
