Oscar Pistorius -- the double-amputee Olympic sprinter -- is now charged with shooting and killing his model girlfriend. We'll tell you what we uncovered about alleged domestic violence in his past -- and what people in her life are saying about the couple. Plus, legendary "The Twist" singer Chubby Checker joins us to vent his frustration over an app that supposedly determines a man's penis size ... because it is also named "Chubby Checker." And, Australian hurdler Michelle Jenneke -- known for her sexy pre-race dance -- will now be known for something else ... her Sports Illustrated bikini spread. Lucky for us ... she joins us via video chat to talk about her foray into modeling.
