Ashton Kutcher, Mila Kunis, and More On-Set Romances

Aug. 7, 2012 — -- intro: It looks like Ashton Kutcher and Mila Kunis' fictional romance has turned into the real deal.

The former "That '70s Show" co-stars -- their characters, Kelso and Jackie, dated on the sitcom -- were seen holding hands as they walked through an airport in Bali early this week. They reportedly spent a week at a 5-star resort on the Indonesian island, and though Kunis has insisted they're just friends, this snapshot and photos of the two getting close at Kutcher's post-party for "Jobs" beg to differ. (Last we checked, platonic getaways don't end hand-in-hand.)
