I guess misspelling and mispronunciation :P It's pronounced zho-LEE in French so if her swimming teacher pronounced it JO-lee and spelled it Joely it has nothing to do with that anymore :P Thanks for looking it up. It is so weird how the name is so common with celebs.
Vanessa's daughter,
Phil Collins' daughter,
Carrie Fisher's sister, some N'Sync singer's daughter. Whoa!
I wonder where the other celebs got it from, or whether they were inspired by
Vanessa's daughter. I think she's the oldest.
