Over the years, Matthew Perry has become known for his role as the hilarious Chandler Bing on "Friends." However, while the actor was making audiences laugh as the sarcastic and goofy character on our TV screens every week, he was struggling with many issues off-camera. Perry has since admitted that he was in the throes of addiction throughout all 10 years "Friends" was on the air, and he also had to deal with unrequited feelings for his co-star, Jennifer Aniston, who played Rachel Green on the sitcom.

In his book, "Friends, Lovers, and the Big Terrible Thing," Perry opened up about his first meeting with Aniston, which came a few years before they were both cast on "Friends."

"I was immediately taken by her (how could I not be?) and liked her, and I got the sense she was intrigued, too — maybe it was going to be something," Perry wrote of his feelings for Aniston. He added that he once excitedly called her to tell her about booking some new gigs but realized it was a "bad idea" to do so.

"Looking back, it was clear that this made her think I liked her too much or in the wrong kind of way ... and I only compounded the error by then asking her out. She declined (which made it very difficult to actually go out with her), but said that she'd love to be friends with me," he added (via Yahoo).
