Washington, Oct 13: Troubled popstar Britney Spears is back to her sexiest self in her new music video, which shows her naked in a sauna.

The 26-year-old star has bared all again for a sizzling promo of her upcoming single ‘Womanizer’.

In the new footage, the ‘Toxic’ star opens the video posing totally nude in a steamy sauna, prompting fans to brand the clip her sexiest to date, reports Contactmusic.

The video is so raunchy that TV bosses had decided to censor the video before it premiered on US news show 20/20 on Friday night, so that her younger fans would not catch sight of the sexy scenes.

Womanizer is the first track to be released off Spears`` forthcoming album Circus, which the singer brands "her best work yet".
