It looks as though the game is up for Ashton Kutcher and Mila Kunis, who have remained coy on speculation surrounding their alleged relationship in recent months. However, the pair were spotted kissing at a party in Los Angeles on Saturday (July 21, 2012), reports US Weekly magazine.

The actor was spotted getting affectionate with Mila during the Los Angeles wrap party for his forthcoming movie 'Jobs', about the late Apple boss Steve Jobs. One eyewitness said, "They were seated on a couch on the same side of the table and Mila was running her hands through Ashton's hair.She had her elbow resting on his back and couldn't stop playing with his hair and rubbing his shoulders.He leaned in and whispered to her and kissed her cheek". Kunis, 28, had firmly denied rumors of a romance back in April, telling Extra, "It's absurd.A friend is a friend", before telling Elle magazine, "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!". The pair have been spotted dining together, road tripping and even furniture shopping in recent months, with one source telling People magazine, "They seem to spend every free second together".

Kunis split from her long-time boyfriend Macaulay Culkin back in 2010, while Kutcher famously split from his wife Demi Moore last fall. According to insiders, Kutcher and Kunis' romance is not necessarily a new development, with one pal saying, "They've been hot for each other for years.It stretches back to when they were friends on their show!".
