Beyoncé has teamed up with Pepsi once again to help cross promote her new cd and upcoming tour. For her newest ad with the brand you can see a collection of all of her past music videos. Including her very first solo hit, 2005's "Crazy In Love"...talk about throwback!

And to throw her a little competition, Taylor Swift has teamed up with Diet Coke and released her new ad today!

Famed haute-couture fashion designer, Jean Paul Gaultier, is the latest designer to collaborate with Diet Coke for their special edition collection. Following in the footsteps of Karl Lagerfeld, Gaultier has designed two signature cans--"Night & Day"--that will be available in Europe later this month. He has also designed a third special bottle but it will not be unveiled until the Fall. What do you think--are they better than Lagerfeld's?
