Denise Richards Patrick Muldoon madeo dinner ex boyfriend hollywood

It's amazing -- neither one of them seems to have aged at all since they dated in the late 1990s!

Last night Denise Richards and Patrick Muldoon had dinner at Madeo, and photogs on the scene observed that they showed up to the restaurant arm-in-arm and looked like more than just friends.

The duo have reportedly been spending quite a bit of time together over the past few months, and Muldoon even met Denises adopted daughter Eloise Joni over the summer. Of course, she went on vacation with ex-husband Charlie Sheen over the holidays, and back in November it was rumored that Denise had reunited former flame Richie Sambora, so it looks like the 40-year-old actress is keeping all of her options open!
