I would have to say that the most interesting celebrity baby name is when gwyneth paltrow named her baby Apple! A lot of people criticized her for naming her daughter that, and I can see why, its not traditional, but if you listen to an interview of her explaining why she named her daugher Apple, it makes a little more sense (sort of):
Gwyneth: “Right, well, um, basically it was because when we were first pregnant, her daddy said, if it’s, basically one day he just said if it’s a girl I think her name should be Apple. And I just, it sounded so sweet, and it conjures such a lovely picture for me, you know apples are so sweet and they’re wholesome, and it’s bibilical and it’s just, they’re so, and I just thought it sounded so lovely and?”
