Hollywood Headlines: A crazy week in review

“Dancing with the Stars” introduced the latest cast of wannabe dancers this week. HLN‘s “Tot Mom” host Nancy Grace and Sonny and Cher‘s daughter-turned-son Chaz Bono got the most buzz.

Martinez, TV personalities Rob Kardashian, Ricki Lake and Kristin Cavallari, singer Chynna Phillips, soccer player Hope Solo and George Clooney‘s ex Elisabetta Canalis round out the lineup.

Talk about a messy breakup. Secret recordings, abuse allegations and extortion investigations are just a few of the headlines over the past year coming out of the Mel Gibson and Oksana Grigorieva split. But all that drama might be behind them once and for all. The former couple, who have a daughter together, finally settled their ongoing custody case.
