Courtney Cox, who is engaged to Snow Patrol rocker Johnny McDaid, claims Coco Arquette, 10, refuses to let her hire a wedding planner as she wants to organise their special day.
The 'Just Before I Go' director said: "Coco is very excited about the wedding. I was going to hire a wedding planner, but apparently she wants to do it. She's 10, but she wants to do everything. She wants to be the maid of honour, which I think is weird. She wants to be the flower girl, all the bridesmaids. She's very excited about it."
Coco was also heavily involved in her father David Arquette's recent nuptials to Christina McLarty and even performed at the event.
Courteney told the 'Ellen DeGeneres Show': "She's loving this wedding stuff. She's a really good singer. I don't know where she got it from.
"She sang 'I Will Always Love You' at David's wedding. That's a hard song!"
The former 'Friends' star fell for Johnny after meeting his family and friends.
She explained: "He's a very sensitive soul. Just a beautiful, sensitive, loving person with a wonderful family, with a beautiful set of friends. Then I was like, 'This is for real!' "
While the couple are excited to tie the knot, Johnny says they are in no rush.
Asked how their plans are going, the 38-year-old star told PEOPLE.com: "We'll get there. I just want to be with this woman for the rest of my life. That is all that matters. The ceremonies are academic."
