Beyonce's Nip Slip

I'm not quite sure if I've seen this in the past, or any other instances of Beyonce Knowles letting the nip slip out of her dress, but here's proof that it happens. This shot was taken while her and boyfriend Jay-Z were on vacation. I wonder if she lets him pay for that. Because, you know, she's an independent woman and all. Oh, that was just a song? Women and their feminism. When it comes down to it, they all just want a sugar daddy.
