Ashton Kutcher and Mila Kunis can’t use the “just friends” excuse for much longer; the two were spotted jetting off for a romantic Bali vacation on Sunday.

Kutcher, 34 — who is still going through a divorce with Demi Moore — whisked Kunis, 28, through Hong Kong airport en route to their exotic love nest.

Exclusive photos show them holding hands, with Kutcher also wrapping a protective arm around the actress’ shoulder. Clearly comfortable with the intimacy, Kunis gently rested her head on her beau, leaving little doubt they are more than just friends.

So have they finally confirmed their relationship? The pair — who have known each other for 14 years since meeting on the set of That ’70s Show — are still remaining quiet, but onlookers say they’ve obviously taken their friendship to the next level.

“They were hugging and appeared affectionate as they stood in a security line,” said one witness. ”They also did a spot of shopping before boarding their plane.” Perhaps Kunis was picking out the perfect bikini for their sun-soaked break.
