Courtney Cox greed to marry Snow Patrol star Johnny McDaid at her 'Friends' co-star Jennifer Aniston's house in June.
McDaid, however, was forced to hastily arrange his proposal as he wanted to involve her 10-year-old daughter Coco - whose father is the actress' ex-husband David Arquette - but the youngster was going away to camp.
Courteney explained: "Johnny first asked Coco. He said, 'I'd like to marry your mom,' and gave her a little diamond ring. 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. "We went to Jen's house for dinner because it was Coco's birthday and she was godmom.
"They made a plan to count down from three and when they got to one, he was gonna get down on his knee and say, 'Will you marry me?' and she was gonna say, 'Will you marry him?' They planned it out. They found the perfect tree that branches that led to one trunk. It was just beautiful."
However, the 50-year-old actress admits her "bored" daughter kept trying to rush Johnny, 38, into popping the question.
Speaking to TV talk show host Jimmy Kimmel, she added: "No one knew this was going to happen because it was just a dinner for, essentially, me and Coco. 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'.
"So, then we go to dinner and there's a salad course or whatever and she's like, 'Oh, my God!' and hits the salad glass, 'Three!' She kept jumping the gun. Finally she waited until after dinner. She was literally about to fall asleep.
