After five years of being together, the comedian/actor Good Luck Chuck proposed to Kelsi Taylor, his singer/fitness coach girlfriend.

PEOPLE is the only one who can reveal. Taylor was asked by Cook to marry him on Wednesday, July 13.

"I was ready to ask her. Cook, 50, reveals that she was totally zen about the whole thing in this week’s issue of people.

"The evening of my proposal was beautiful. The weather was perfect. The sunset was breathtaking. I was simply so happy."

Cook said that he had been planning the proposal for months, and finally decided to make it happen on a trip down to York Beach.

He had planned this for months and designed the ring.

Cook said it was the best feeling ever and that they sat down together on the deck to share laughs and hold hands.

It was amazing to see how he coordinated everything seamlessly, even though it was all just a dream. It was a moment of pure bliss.

Cook shared that he and his fiancee had made "a lot of plans" and "set many goals" for the future.

I am about to spend the rest of my life with my best friend and favorite person.
