Jennifer Aniston's crush has spoken out and revealed various details about their relationship back when they were much younger. Although they were only 12 when they first kissed, Aniston – then Anastassakis – was described as "very open" by classmate Adonis Tsilimparis.

Jennifer Aniston's crush back the seventh grade used to do what seventh grade kids do: sneak into staircases to "make out," he told The New York Daily News.

"She was very open, very, very sweet," Tsilimparis said. "She was very, very loving, and she had a very big heart."

His proof of his short relationship with the future superstar? A Valentine's Day card that reads "Love & Friendship Always. Love Ya. Jennifer A."

Even though the youthful puppy love was over 30 years ago, Adonis, who is now a composer for TV and movies, said that the relationship never went anything further than their young make-out sessions.

"I tried. But she didn't let me … We used to go to the back stairs at school at lunchtime and make out," Tsilimparis explained. "She was just goofballs … But that's why I loved her."

"Total clown, very lovable and that's why everyone liked her," the 43-year-old added.

Though he didn't remember why their relationship ended, another classmate who dated her, Tom Friedner, said that Adonis called it quits.

Though she may have dated Tsilimparis then, Aniston revealed that her other crush was much different. Simon Le Bon of Duran Duran captivated the future Hollywood star at a young age.

"[Le Bon] was a big crush at 12. I was a major Duran Duran fan. Shaun Cassidy too," she told InStyle magazine U.K. "I don't know what it was about him – his hair, puppy dog eyes and mushy mouth?"

Now, Aniston is engaged to fellow movie star Justin Theroux, although the couple has not confirmed when the wedding will be.
