4. Blonde Ambition

Brit was pretty much on top of the world in the career world in 2004. Her newest album sold 609,000 copies, making her the first female artist whose first four studio albums all debuted at number one on the charts. Her personal life, on the other hand, was a little rockier. She married her childhood friend Jason Alexander in Vegas in January 2004 and a whopping 55 hours later had the nuptials annulled.
