Moore, 48, and Kutcher, 33, were dressed up for a service, according to X17, and both were wearing their wedding rings.
"While Ashton pulled up in their black Lexus, Demi exited out of a side door of the Kabbalah Centre and quickly jumped in the car. She clearly did not want to be photographed," said an X17 photographer who took photos at the scene.
The couple has dealt with the rumors about their marital discord over the past week over Twitter. Amid a flurry of new tabloid reports about Kutcher's alleged infidelity, the actors and avid social media users took to Twitter to hint at how they're handling the situation.
Early Thursday morning, Kutcher tweeted a link, without comment, to his Spotify account, where he was playing the Public Enemy song "Don't Believe the Hype."
Moore started stirring the pot in September, when she tweeted a photo of her naked back with the message, "remember.....you've got your own back." She seemed more direct on Sept. 23, when she tweeted a quote from Greek philosopher Epictetus, writing, "When we are offended at any man's fault, turn to yourself & study your own failings. Then you will forget your anger." On Monday, she wrote "I see through you...." and linked to a photo of herself lying down with her eyes closed, her mouth drawn in a line.
Beyond the tweets, there's evidence to suggest unrest: The couple spent their sixth wedding anniversary, Sept. 24, apart. While Moore promoted the short film she directed for Lifetime's "Five" anthology in New York, Kutcher partied with his former "That '70s Show" co-star Danny Masterson in San Diego, according to People magazine.
The two have been spending a lot of time on separate coasts. Moore's been in New York working on her upcoming movie "Magic Mike," while Kutcher's busy filming "Two and a Half Men" in Los Angeles.
The couple has weathered this storm before. Last year, amid tabloid reports that Kutcher had cheated on Moore, the couple embarked on a spiritual trip to Israel. At the time, Kutcher tweeted, "Asking 4 the energy 2 forge bonds with our similarities & find compromise in our differences."
What's their status now? Reps for Moore and Kutcher did not respond to ABCNews.com's requests for comment, and with the stars' workload, it's unlikely a romantic getaway is in the cards anytime soon. But getting together to take a couple cutesy twit-pics couldn't hurt their case. Kutcher may be realizing that -- he walked around in L.A. Thursday flaunting his wedding ring.
"Usually they brush these rumors off and let Twitter speak for them," said People magazine reporter Carlos Greer. "What's interesting, right now, is that they're not posting the lovey dovey photos that they normally post."
