ACTRESS Lindsay Lohan prepares to take off her robe for Playboy – with a quick ciggy.

The picture, obtained by US website TMZ.com, shows the star puffing away before the Marilyn Monroe-inspired photoshoot.

According to TMZ.com, the picture was taken behind the scenes during Lindsay’s two-day shoot back in November right before she bared all for the top-shelf magazine .

In the Playboy photos, which leaked online last week, Lindsay poses naked except for a black stole around her shoulders, and draped all over some red sheets.

The black stole comes off for the later shots, and Lindsay gets fully nude. She holds her boobs and flashes her bum, and looks very comfortable in front of the camera.

After posing for Playboy, she went on a knobbly-knees-up in Hawaii where she was spotted with a new mystery man.
