Britney Spears has been a busy lady recently traveling around Europe to promote her latest album Circus. She received a Bambi award, appeared on X Factor and today celebrates her 27th Birthday! I have decided to use the occasion to look back at Britney's ever-changing style over the years. From a fresh-faced girl next door to appearing on stage in her tribute to Madonna, Britney is never one to shy away from a publicity grabbing outfit! Who can forget the MTV awards 2001 when she performed with a live snake and some very tiny hot pants, or the VMAs 2002 when she wore a racy leather clad ensemble? See below for images of the star from 1999 to the current day and join me in wishing Britney a very Happy Birthday!

After checking the gallery why not see how well you know Britney.
