Their reps still deny that former costars Ashton Kutcher and Mila Kunis are an item, but their appearances together seem to show that something's going on with Kelso and Jackie again. The That '70s Show costars shared a cozy sushi dinner a couple of weeks ago, and a photographer said the two looked quite cozy: "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!" Last weekend, they were spotted enjoying a long weekend getaway in the beach town of Carpinteria, Calif. A source told People that the relationship was a long time in the making - Kunis dated Macaulay Culkin while she and Kutcher filmed That '70s Show, though he always had his eye on her. "He was so in love with her for a while when they worked together," revealed the insider. "He thought she was a goddess, was always talking about how beautiful she is. But she was with Macaulay (Culkin) for a lot of that time and also just generally gave off a not interested vibe." Things definitely look interesting now - the time is right with Culkin and Kutcher's ex-wife, Demi Moore, out of the picture. Let the rekindling begin!
