Everyone who has watched That 70s Show, must have a good memory of Ashton Kutcher and Mila Kunis as a couple.

Hanging out as friends, playing around, fighting and kissing, they were a great duo on the screen. But there is something interesting amid all the rumors of the two dating.

Ashon Kutcher is the first person the Black Swan actress has ever kissed! It was during one of the romantic moments on the sets of That 70s show that the duo locked lips.

So now we know why their bond of friendship has been going so strong and for so long.

Kunis, now 28, was just a teenager back then and everyone knows that the first kiss always has a special place in one's heart. Is that what the latest rumors are all about?

The fact has been dug out by People Magazine which revisited an interview with Kunis in the year 1998 where she admitted that Kutcher is the first one she ever kissed.

Then 14-year-old Kunis had said I was like, Oh, he's so cute, it's the Calvin Klein model!

Then I was like, I have to kiss him?' I was so nervous and uncomfortable. I had the biggest crush on him.

She had also revealed that to make herself feel better and get herself out of nervousness, she sprayed some perfume. I totally perfumed myself and I was like, 'Hey, I feel better about myself! she said.

Kutcher, now 34, admitted in 2001 that it was shocker for him to know that he was the first person ever that Kunis kissed. I'm the first guy she kissed? Oh my god, I had no idea! I'm so glad I didn't know that or it would've been too much pressure, he had said.

After visiting a bit of the past, it does not seem too difficult to imagine that Kelso and Jackie from the show perhaps could date after all these years.

Kutcher and Kunis have been spotted together spending some cozy time over the weekend. Both friends have recently come out of long-time relationships. While Demi moore filed for a divorce from Kutcher last year November, Kunis also broke-up with boyfriend Macaulay Culkin in January this year.

However, the friends have denied all rumors about an affair between them.

A representative of Kunis told Celebuzz They've been friends for years, and they had dinner with a bunch of friends. They're not dating.

As for Ashton Kutcher, he has been linked with half the Hollywood beauties so far. After allegedly breaking ex-wife Demi Moore's heart on the night of their wedding anniversary, he is already rumored to have dated almost half a dozen women including Rihanna, Lorene Scafaria and Mila Kunis, with the latest being an unidentified blonde woman.
