It's a fine line between finding inspiration from someone you admire to following a little too closely in their footsteps, which is something these celebs can't seem to separate.

Lily Allen and Jaime Winstone

First up, Lily Allen and Jaime Winstone. Not only are these two the same age (sprightly 22-year-olds) and firm friends after Jaime bagged Lily's younger brother Alfie as her current squeeze, but the cool London duo appear to share similar tastes when it comes to all things fashion. Sometimes it's punkish street-style looks they plump for, other times it's full-on grown-up chic, but whatever the look these two always have bags of attitude.
