Ashton Kutcher and Mila Kunis have been a couple for years. Why's everyone so surprised now? Oh yeah, that was just on TV.

The stars, who met and played a couple on TV's "That 70s Show," have tried denying lately that they are anything more than just friends.  But photos of the two kissing, holding hands, and going on dates around town, have us thinking otherwise. On August 14 Kunis even visited her not-so-secret boyfriend on the set of "Two and a Half Men."

According to a fan that was at the taping, there were no doubts Kutcher and Kunis were together. It's not clear if the two were seen all over each other or showed any concrete proof of their relationship, but the fact that Kunis visited Kutcher does slyly nod in that direction.

Kutcher and Kunis can try to deny their romance all they want, but "friends" don't make out and go on romantic vacations together... unless of course they are "friends with benefits"-and Kunis should know all about that since she starred in a film with the same name.

"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," said Kunis a few months ago. Many, however, would beg to differ. It seems as though something has grown between these longtime friends, and they really can't deny it any longer.

Kutcher and Kunis may or may not come clean about their romance, but at this point, they're certainly coasting into relationship territory.

Of course, even if that's the case, that doesn't necessarily spell marriage for the couple's future. As she put it in a recent interview with More! magazine, she doesn't understand the "need" for marriage.

She told More! magazine: "I would love to find 'The One'. But I'm not sure about marriage. I see no need. I'll be with somebody because I want to, not because a piece of paper tells me I have to. That said, if the love of my life thinks it's important, then fine, I'll get married."

While Mila would be happy to marry if her partner was keen, she doesn't see the point in making "sacrifices" for a significant other and has met far too many men with commitment issues.

The actress - who previously had a long-term relationship with Macaulay Culkin - added: "You have to make compromises, but I don't believe you have to make sacrifices for love...I've met plenty of guys with Peter Pan syndrome, where they don't want to grow up."

If that's the case, glad she hooked up with the paragon of maturity. Now we just have to wait for their televised "wedding" on a new season of "Punk'd." God, I hope Kunis wears a trucker hat veil.
