Spencer Pratt Gunning for Something

Reality star turned psycho Spencer Pratt's behavior goes from bizarre to beyond frightening every day -- and now the loose cannon is armed and dangerous. In fact, he wants the world to know that he's slowly building his own personal arsenal. It wouldn't be so frightening if Pratt hadn't threatened to get violent in the past. Pratt publicly pointed out that he boosted his gun collection over the weekend. He Tweeted, "Just bought a new Colt .45 and a new Glock. Nothing like buying some more pistols on a sunny Friday in LA." Since being fired from The Hills for threatening to kill a female producer, Pratt has begun venturing into new territories. He's apparently trying his hand as a reality show producer, film director and a paparazzo. And who can forget gun enthusiast? Just this week, Pratt proved how unpredictable he is when he showed up to The Hills live finale dressed as an old man. According to one insider, Pratt's fellow cast members were so afraid of what he might do that they turned out armed to protect themselves. Says the source, "For someone who was such an integral part of the show, he was not even allowed at the curb. The talent are really physically afraid of him. Lauren Conrad had a Taser in her bag." We doubt that Taser would be any match for Pratt's Colt or his Glock. Pratt promises that drugs are not the impetus behind his bad-boy persona; he simply loves to be loathed. "My high is how much people hate me."
