In 1998, Ashton Kutcher, 20, and Mila Kunis, then 15,
both got their big break when they were cast to play on-again, off-again
couple Kelso and Jackie in the sitcom “That ‘70s Show,” that would go
on to run for eight seasons beginning in 1998. As part of the job, Kunis
found herself sharing her first kiss — both on- and off-screen! — with
Kutcher, a guy she recognized from ads. “I was like, ‘Oh, he’s so cute,
it’s the Calvin Klein model!’” she told People
in 2001. “Then I was like, ‘I have to kiss him?’ I was so nervous and
uncomfortable. I had the biggest crush on him.” Kutcher later admitted
that he was just as nervous! (Undated)
