richards sambora getty Have Denise Richards and Richie Sambora reunited?If at first you don’t succeed, try again. That seems to be the motto of actress Denise Richards and Bon Jovi guitarist Richie Sambora who are apparently back together.

RadarOnline is reporting the couple were seen dining together at a Los Angeles-area restaurant on Sunday (Oct. 30). The two dated from 2006-07 after their high-profile divorces from Charlie Sheen and Heather Locklear. The situation between Locklear and Richards was particularly hairy because the two were, at one time, very good friends.

Radar cites a source who says, “It is serious but they are trying to keep it low key.”

The last few years have been a challenge for Sambora who twice checked into rehab. The most recent of those stints, which happened in Spring 2011, resulted in him missing out on tour dates with Bon Jovi.
