Richie Sambora and Heather Locklear
The couple wed in 1994 in Paris, France, shortly after the actress' divorce from Tommy Lee. She and the Bon Jovi guitarist had daughter Ava in 1997 before divorcing in 2006; Locklear's pal, Denise Richards, was linked to Sambora soon after. "I did not steal someone's husband," Richards later told Us. "Did I date a former friend's ex-husband? Yes. Did I break up a marriage? No."
