After persistent denials about their increasing proximity, Ashton Kutcher, 34, and Mila Kunis, 28, were spotted kissing and cuddling at the wrap party for his Steve Jobs biopic.
"Despite being surrounded by a host of fellow attendees at the Hollywood venue, Ashton and Mila only had eyes for each other. They were seen sharing a kiss and put on a tactile show, with Mila caressing Ashton's face and putting her arm around him," reports Daily Mail.
Last week as well, the rumoured lovebirds went on a romantic motorcycle ride in Hollywood.
The That 70s Show co-stars, who played high school sweethearts on the sitcom, have been hanging out since late April and doing everything - from road trips to dining out in public - together.
Mila Kunis' denials
The Black Swan actress, who has been spotted on a string of dates with the actor and long time friend Ashton Kutcher, who split from his wife Demi Moore last November, refused to confirm the relationship but insists that if she did want to date, it wouldn't be workable.
"Is a guy going to come up to me and ask if he can take me out on a date? Where can I go and have this date? I can't go anywhere. My house, his house...So what do you do? I'm trying to be like a normal girl and a single girl... but the concept of being single and in my position is just not workable. I couldn't even go on a date if I wanted to," she told Elle magazine.
Ashton Kutcher and Mila Kunis played high school sweethearts in That 70s Show.
She was spotted sharing a cozy meal with Kutcher in Los Angeles last month, but maintained he is just a friend. "I am totally single... Listen, we hang out. We've known each other for 15 years. We have mutual friends. We're comfortable with one another. That's it! There's no crazy love story, nothing more," she told Elle.
Since Kunis insists on being just friends with Kutcher, we wonder if they are 'friends with benefits' or is she just lying about their relationship status!
