Lauren Conrad is a pink lady!
The former star of "The Hills" showed up to a signing of her latest book, "The Fame Game," last night at The Grove in Los Angeles -- where she was sporting a shocking new look.
Instead of the lighter locks we're used to seeing on LC, the back of her head was hot pink.
While the singer with the same name made the color popular back in the day, pink is becoming a hot color again -- and was recently spotted on the heads of January Jones, Chloe Moretz, Britney Spears, Joan Rivers and even Amanda Bynes ... in her mugshot!
