• Chaz Bono is the incredible disappearing man — ’cause dude has nearly shed a whole Honey Boo Boo worth of lbs since dramatically changing his diet last year. Chaz was barely recognizable as he was spotted in Los Angeles today … walking around in shorts and a pretty tight tee-shirt. Earlier this year, Chaz talked about how he dropped nearly 70 pounds — not through surgery — but through sticking to calorie-controlled meals … and doing a ton of martial arts training. He has lost nearly 100 pounds
• John Cussack’s stalker was caught in the act. John Cusack’s Miami mansion was met with a home invader Tuesday evening. 45-year-old Elizabeth Pahlke, who allegedly has a “serious thing” for the actor, attempted to climb in through the window, before scaling the fence, all caught on Cusack’s security cameras. Pahlke was later taken into police custody. She was charged with stalking and burglary, and is being held on $150,000 bail. Her attempt at having a sleepover with Cusack comes after Pahlke was served with a restraining order earlier on Tuesday. Cusack was not home at the time.
