Apparently tennis star Lleyton Hewitt influences people with more than just his backhand:  according to the Sydney Morning Herald, since Lleyton and his wife Bec named their newborn daughter "Mia," in November, the girl's name has catapulted to one of the top ten girl's name choices in Australia. 

Registry spokeswoman Alana Sheil said it was possible the rapid climb was due to the celebrity factor.  "It's a bit of a trend for parents that they like to choose the same names as celebrities," she said.

Hmm.  Personally, I think "Mia" is a lovely name, and I'd consider it despite what celebrities chose.  But I suspect that the allure of celebrity babies that Larissa Brown mentioned does have something to do with the rise, as well.
