From the experts:
There are no less than ten different variations of Hailey on the current Most Popular list, but this is the spelling that brought it into the Top 10 of 2010, although it has recently dipped a bit in popularity. So, although Hailey has a shiny, unpretentious charm, its mass popularity makes it very much of the moment. Look for the Hailee spelling to rise via Hailee Steinfeld, the young actress Oscar-nominated for her performance in True Grit.
