Bon Jovi guitarist Richie Sambora and actress Denise Richards have rekindled their romance four years after their split.

Richie, 52, and Denise, 40, started dating in 2006, following Richie's divorce from actress Heather Locklear and Denise's divorce from actor Charlie Sheen. The romance, which some labeled as a rebound relationship for the two newly divorced stars, ended after a year of dating.

Now, it looks like the twosome have decided to give their relationship another go and have been spotted on several romantic dates, including a dinner on Sunday night (Oct. 30) at a Japanese restaurant in Woodland Hills, Calif., according to RadarOnline.

A source told E! "They're very happy and are dating. They never stopped caring for each other." In fact, Denise wrote all about her relationship with Richie in her tell-all memoir 'The Real Girl Next Door,' revealing, "Richie and I shared an easiness I hadn't before had. We were able to be open, honest, and completely authentic with each other, with no judgment."

She continued, "I don't regret my relationship with him. I learned hard lessons from our journey together. My heart may have been bruised, but it was pure. Richie is a wonderful man. He came into my life when I needed him and he needed me. We'll always have that bond."
