I’m not sure this qualifies as a nip slip — it’s more along the lines of a straight up Janet Jackson wardrobe malfunction. And let me just go on the record and say that I’m not a fan of that bikini style for the looks. But if it keeps producing results like the following, then I might become a bigger fan.
Disclaimer: I typically make a point to ignore all things Paris Hilton, but this is something I can make an exception for.
