Lindsay Lohan is set to shock in a racy new photospread for French fashion magazine Purple.

The star appears topless in a series of sexual poses in the provocative Terry Richardson shots, which will feature in an upcoming issue of the publication.

In one steamy snap, Lohan simulates a threesome with a male and female model, according to magazine Life & Style, which has obtained the pictures.
