This really weird video that starts out with Taylor Momsen and ends with an equally bleached blonde stunt double is:
a) Part of Nike's new underground campaign - note gratuitous shots of Little J's sports bra's swish and insanely bright Nike sneakers.
b) Part three of Gossip Girl's sneaker invasion, Ed for KSwiss, Leighton for Reebok? (Can Chace land Puma? Will Blake follow up her Vogue cover with an Adidas campaign? Will someone on Gossip Girl actually wear sneakers?)
d) Part of something we don't know about, and you're going to tell us...
