But she soon stripped off to catch some rays in the Californian sunshine, but stopped shy of completely removing the dress, to conceal the drink-monitor tag.

Lindsay spent the day at Polaroid Beach House in Malibu one of the most photographed spots in LA. She's desperate to send out a message that she's recovering after her rehab stint, but didn't want to give her tag another airing.

She seemed relaxed, and spent time playing with her pal's children, despite the attention her presence on the beach generated - as the ever-present bank of paparazzi detailed her every move.

Grafiti girl: Lindsay left a message on the toilet door of a pizza restaurant

According to US magazine People, Lindsay has started dance lessons in the art of the Tango for a new movie role.

An official announcement is expected this week for Lohan to co-star in the biopic of Tango legend Carlos Gardel.

Set in 1920s Buenos Aires, Dare to Love Me, tells the story of a steamy romance between Gardel and a prostitute whose world is shattered by a bullet that kills her and leaves him crippled with a fragment in his lung for life.

Lohan's exact role in the film has not yet been confirmed, but sources close to the star said she begun taking hour long lessons – all while wearing the alcohol-monitoring ankle bracelet she's had on her leg since emerging from rehab on July 13.

After sunning herself, Lindsay headed to a pizza parlour in Hollywood where she indulged in a spot of grafiti in the men's toilets.

She scrawled in a black marker: "We love our boys" and "Frankie my love thanks for taking care of me and feeding my crew. Stay sexy."
