Justin Bieber is scared what cops are going to find on his cell phone… his issues involve nakedness and drugs! He’s not so much concerned about the eggs. Law enforcement sources say that when they searched Justin’s house Tuesday, they seized his cell phone, took it right out of his hands. Sources say cops are interested in texts that could incriminate him. Cops want to see if he texted someone after the fact and bragged about the egging. One law enforcement source called it a “text high 5.” Sources connected with Justin tell TMZ, “He’s concerned more about drug discussions and references. Even if cops find drug references, Justin’s in the clear given there’s no physical evidence — nonetheless J.B. is afraid it will leak out. He’s also concerned that there are naked photos in his phone, although no word if they’re action shots, selfies, etc.”
