Other than a brief hiatus in 2006, Britney Spears has been in every single 100 Sexiest list since 1999. That's not bad for a world-famous megastar who's had more ups and downs than Nemesis Inferno at Thorpe Park.

Do you think, after 15 years in FHM 100 Sexiest, Britney deserves the title of Sexiest Woman Of All-Time? Then head over here.

Check out her sexy legacy right here...

1998

Britney's first single, Hit Me Baby One More Time, is probably one of the best debuts in pop history. Catchy tune? Check. Controversial costuming? Check. Insanely hot girl? Checkity check.

 

1999

The first album, ...Baby One More Time, is released, with the single (You Drive Me) Crazy, promoting excessive use of brackets in song titles and reminding us of Sabrina the Teenage Witch.

 

2000

Britney churns out a second album, Oops!..I Did It Again, within a year. We'd question it but we're too busy gawping at this video.

 

2001

Really? Another album, already? Who cares, she's at the VMAs with a bloody albino python on her shoulders.

2002

Britney makes her big scree debut in Crossroads. This is the only good thing about it.

 

2003

The now-legendary Britney and Madonna kiss happens at the VMAs and no one really cares that Christina Aguilera was in on the action too.

 

2004

The same year that this awesome video for Toxic comes out, Britney wins FHM 100 Sexiest Women In The World. Coincidence? We think not.

 

2005

What goes up must come down, as things start to go awry with a Las Vegas wedding/annulment and then a second marriage in the same year.

 

2006

The year that things finally went to pot after years of being on top of the world.. Head-shaving, umbrella attacks and THIS guy all happen.

 

2007

Britney makes a comeback with the album Blackout and this performance of single Gimme More. She returns to FHM 100 Sexiest at a respectable #54.

 

2008

Fast forward one year and she's naked, in a sauna and looking back to her sexy best in the video for Womanizer, off the Circus album.

 

2009

It's time to catch up with the raunchy likes of Rihanna, Beyonce and Lady Gaga. Cue the gasp-once-you-realised-it's-naughty If You Seek Amy and 3, a song about threesomes.

 

2010

2010 is the year Britney takes a chill pill on the music front. Here she is in her very own special episode of Glee, not long before releasing a clothing line.

 

2011

Must be time for another album. 2011 brings Britney's 8th studio album, Femme Fatale, and such self-reflective and apocalyptic bangers as Hold It Against Me and Till The World Ends.

 

2012

Britters replaces Scherzinger on the US version of The X Factor. She judges peoples based on the quality of their vocal talents...

 

2013

She lands herself a two-year residency in Vegas, where everyone from Miley Cyrus to Katy Perry pays their respects on the front row to the Princess of Pop. She wears things like this.

 

2014

She's still in Vegas and enters FHM 100 Sexiest for another year at #59. The world is amazed that, despite being hidden in the Nevada desert, she still manages to overtake the likes of Jessica Alba, Candice Swanepoel and Rosie Huntington-Whiteley.
