and Mila Kunis
enjoyed some serious alone time together during an escape from L.A. last weekend.
The longtime friends and That '70s Show
costars went on a three-day getaway to the coastal town of Carpinteria, Calif., just south of Santa Barbara. While away, Kutcher, 34, and Kunis, 28, dined on sushi, shopped for fruit and flowers and spent plenty of time in private.
After driving up from L.A. together last Thursday, the pair were spotted grabbing a quiet sushi lunch for two the next day. Later that day, Kutcher looked on while Kunis bought sunflowers and blueberries at a roadside fruit stand.
They weren't spotted out on Saturday but made a coffee run the next day before driving back to L.A., where a solo Kutcher took in the Lakers game court-side.
Last week Kunis's rep denied rumors that the pair were an item after they were spotted going to dinner with friends
and reportedly shopping for furniture.
Neither rep would comment on their weekend outing, but a Kutcher source tells PEOPLE that the Two and a Half Men
star has long held a torch for Kunis.
"He was so in love with her for a while when they worked together," says the source. "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."
Adds the source, "It never happened, but I'm not surprised by this – at all."
Still, another source close to the actor says Kutcher isn't looking for romance right now: "He always talked about Mila like a little sister. They're definitely close pals and have been. I think if anything she's a good time for him. But he's not looking for anything serious."
