Richie Sambora and Jon Bon Jovi are going at it as if they Richards and Jagger! Richie's bailing on their tour ... and we know what it's gonna take to put the band back together. Plus, Justin Bieber's so busted up over Selena Gomez that he's taking it out on the world?? That's what some people close to JB think -- but are you buying that from a 19-year-old filthy rich superstar? Also ... Conrad Murray's rambling voicemail message, and absurd serenade to Anderson Cooper have a lot of people convinced he's totally lost it. Just in case the whole killing Michael Jackson thing wasn't enough.
