Couple Nickname: None
Dated Between: 2006 – 2007, 2012

Denise Richards’s relationship with Bon Jovi guitarist Richie Sambora began in 2006, almost immediately after Sambora called it quits with his wife of 12 years, Heather Locklear, Denise's best friend. Sambora and Locklear even have a kid together. Despite Locklear publicly giving the two her blessing, the love triangle was front and center in the tabloids, with reports of nasty name-calling and backstabbing taking up the pages.

The couple were on and off for a while—they fought like cats and dogs, a lot, big surprise—until June of last year when they got into a huge fight in Nashville. Apparently, Richie ditched both Denise and Willie Nelson at the CMTs when he was supposed to present an award, and this didn’t sit well with her.
