Jessica Simpson Quotes

They're just the cutest couple in the world. They are adorable. Anybody would wish to be them and you can only wish them well. Just being around them inspires love and everything I sing about.

Jessica Simpson [on her sister and Pete Wentz]

It’s fun to do a small film that might be released to DVD not because it’s a horrible film, but because it’s an independent film. For people to say Employee of the Month was a flop is ludicrous. We made the money back–that’s not a flop. For people to say The Dukes of Hazzard was a flop–it opened to $30 million! If these movies are flops, why would I still make them?
