Lindsay Lohan is showing off her sexy side in a new photo taken by controversial photographer Tyler Shields.
The 27-year-old actress took to Instagram to post the picture, in which she is in a swimming pool, striking her signature finger-in-mouth pose. She captioned the photo, "@thetylershields come to #nyc."
Shields' book, "The Dirty Side of Glamour," will hit stores on Nov. 12. He's throwing a launch party on Nov. 9 at the Guy Hepner Gallery in Beverly Hills, Calif., which Lohan has been invited to attend.
