Before he popped the question to Courteney Cox, Johnny McDaid enlisted a little help from her 10-year-old daughter, Coco.

"Johnny first asked Coco. He said, 'I'd like to marry your mom,' and gave her a little diamond ring," Cox recalled on "Jimmy Kimmel Live" Monday night. "She said, 'Great, I'm going to camp tomorrow. Let's do it right now.' So, they decided they wanted to do it that night because we were leaving for Turks and Caicos and she was going to camp."

That night, they were having dinner with Coco's godmother, Jennifer Aniston. So Cox said they came up with a plan "to count down from three and when they got to one, he was going to get down on his knee and say, 'Will you marry me?' and she was going to say, 'Will you marry him?' They planned it out. They found the perfect tree with three branches that led to one trunk. It was just beautiful."

But it didn't go quite according to plan.

"Coco got a little bored, as she does, and right after we were at the bar having a drink, she said, 'Three!' Johnny's like, 'No, not now!' So she's like, 'All right,'" Cox told Kimmel. "So, then we go to dinner and there's a salad course or whatever and she's like, 'Oh, my God!' and hits the glass, 'Three!' She kept jumping the gun."

Cox said McDaid finally proposed after dinner, but by then Coco "was literally about to fall asleep."

The next day, the "Friends" star and her finance basked in the glow of their engagement on Turks and Caicos, but Cox said that after four days of utter bliss and solitude, she was ready to make some friends.

"I could not make a friend! I tried so hard! It must've been my hair," she joked to Kimmel. "No one wanted to talk to me so it was really bad. I was like, 'Gosh! Monica! Friends!' Nothing!"

Finally, on their last day, she said, "Someone swam up to me and said, 'I just want to say I'm a big fan of Friends. Can I get a picture?' I'm like, 'Are you kidding? A picture! We're eating lunch together!'"
