Britney Spears has fallen out of the list of the world's 100 sexiest women - two years after topping it.

The singer, 24, was crowned the sexiest celebrity on the planet in 2004, and last year made sixth place.

Now the former pop princess isn’t getting enough votes to stay in FHM magazine's 100 Sexiest Women in the World.

FHM editor Ross Brown said: "A couple of years ago, FHM readers couldn't get enough of Britney, and they unanimously agreed that she was by far the sexiest woman on the planet.

"It's hard to believe that she’s currently outside the top 100 – I can only guess that a raft of less-than-flattering photographs and her general disappearance from our TVs and radios have left readers under the impression that Britney's lost her sex appeal."

Britney may have fallen from favour, but other mothers and pregnant women in the top 50 include Kate Beckinsale and mother-to-be Katie Holmes.

Britney is around 20 places outside of FHM"s 100 sexiest list, lagging far behind the likes of Joss Stone and Charlotte Church.

The former chart topper will need around 20,000 votes to make it into the top 100.
