Vanessa Paradis would be "terrified" by a traditional wedding.
The French actress-and-singer - who has been dating actor Johnny Depp since 1998 - admits she hates the thought of tying the knot in a lavish public ceremony.
She said: "A conventional ceremony with lots of guests, a church full of flowers and huge amounts of money being spent is in no way appealing to me. I think I would find it more terrifying than anything else."
The 37-year-old beauty - who has children Lily-Rose, 11, and Jack, eight, with Depp - also admitted the couple hate spending time apart, and feels the constant travelling the family do to stay together is beneficial.
She explained to Britain's Hello! magazine: "We can't be apart for long. The kids like it too. I hope it will make them broad-minded and open. As long as they have everything they need - which is a lot, about 40 bags - then we have as normal a life as possible."
If they do have to spend time apart, the couple rely on internet video calling software Skype to communicate, but Vanessa admits she hates having to say goodbye to her 47-year-old partner.
She added: "Skype is OK but I wouldn't want to do it every day, it's so hard to press stop. It's bad enough hanging up a phone, but hanging up an image - I can't do that."
