Anna Nicole Smith's former bodyguard has dubbed her companion and lawyer HOWARD K. STERN a liar after he went public with denials he administered drugs to the tragic model/actress. Moe `Big Moe' Brighthaupt was shocked when Stern insisted claims he gave his late girlfriend drug injections were "absolutely false" during a recent TV interview with Larry King - because he'd seen him do it. The bodyguard tells U.S. news show Access Hollywood, "He lied about that and he can't refute that because I've been there all the time." He recalled occasions when Stern injected Smith with drugs, adding, "(He told me it was vitamin) B12. On some occasions, yes, I believe it was B12, on other occasions it was something else." Brighthaupt tried to revive Smith as she lay dying in a Florida hotel suite in February (07).
