Are Ashton Kutcher and Mila Kunis Dating?

Six years after they played young lovers on "That '70s Show," Ashton Kutcher and Mila Kunis seem to be taking their relationship from reel to real. The two were photographed leaving a Japanese restaurant on Sunday night, capping off a day-long date. Earlier that afternoon, the actors — who coincidentally both starred in 2011 rom-coms about pals-turned-lovers (Kunis starred with Justin Timberlake in "Friends With Benefits" and Kutcher played opposite Natalie Portman in "No Strings Attached") — shopped together for furniture to fill his new Hollywood Hills home, where he moved after splitting from Demi Moore amid reports he cheated on her.

An eyewitness told X17 Online that the twosome looked anything but platonic during their dinner date. "Ashton was touching Mila's hand and Mila was all dressed up. She looked hot. This was definitely more than a dinner between friends — this was a full-on date!" But when it was time to head home, Kutcher, 34, and Kunis, 28, suddenly got shy as they walked to his car. Covering her face, the "Black Swan" actress, clad in tight pants and sky-high heels — hopped into the back seat, while he got behind the wheel. It was reportedly also not their first time out as a couple. According to X17, Kutcher and Kunis have spent the night at each other's homes frequently in the past few weeks.

Although it certainly seems like something is going on between the actors, a pal close to Kunis tells Us Weekly that the duo is "so not dating. They've been friends for years. But she would never ever [be with Kutcher]. Definitely nothing going on there."

But if they really are dating, Kunis would be the latest in a string of women the "Two and a Half Men" star has been linked to since separating from Moore, 49, in November after eight years together. Just last month, Rihanna was spotted leaving Kutcher's bachelor pad in the wee hours of the morning. The pop star has been asked about it twice during promotions for her upcoming film, "Battleship" — and both times she has rudely shut down the interviews. Before Rihanna, Kutcher was seeing writer-director Lorene Scafaria, who he spent the holidays with in Italy, just weeks after calling it quits with Moore.

In stark contrast, Moore has mainly stayed single and out of the public eye … except for that rehab stint.
