Denise Richards and Nikki Sixx have come out of hiding.

One week after Us Weekly broke the news that Richards, 39, has been quietly dating the Motley Crue bassist, the couple was spotted hand-in-hand outside a movie theater in Calabasas, California Thursday.

After seeing Little Fockers (which Richards deemed "very funny" on Twitter), Sixx, 56, tweeted that he had a "full-on positive day" with the Blue Mountain State actress.

Though the duo are currently thousands of miles apart — Sixx is vacationing in Mexico while Richards is soaking up the sun in Hawaii with daughters Sam, 6, and Lola, 5 — a source tells UsMagazine.com the two aren't looking to settle down anytime soon.

"They are still taking it slow but having a great time together," the insider tells Us. "They aren't going to be together for New Year's, but of course they will talk the whole time and see each other right when they get back!"
