When: 2007-2008

After 12 years of marriage, in 2007, rocker Richie Sambora and the timelessly hot Heather Locklear filed for divorce, citing irreconcilable differences as the cause. Just months after the split, the legendary Bon Jovi guitarist began dating one of Locklear's best friends in the world, comparably hot actress Denise Richards, who, after a tumultuous break-up with Charlie Sheen, found herself newly single as well. The hook-up effectively put a temporary end to the long-time friendship of Locklear and Richards. And although everyone has since reconciled and are on good terms, for a while there, Heather wanted both Sambora and Richards more dead than alive.
