Lindsay Lohan is reported to have been cast in a music video from Lady GaGa's forthcoming ARTPOP album.
The New York Post's claim follows a recent picture posted by GaGa on her Little Monsters website, where she posed with Li-Lo and another friend at Hollywood's famous Chateau Marmont.
A source told the paper: "Lady GaGa and Lindsay caused a stir last month when they had their ‘sleepover’ at the Chateau, and now it turns out that Lindsay will be starring in GaGa's new video from her upcoming album.
"Due to GaGa's superstar status, this would be Lindsay's biggest [role] by far in many, many years."
Li-Lo was also this week confirmed as starring in the forthcoming comedy sequel Scary Movie 5 - and is currently filming The Canyons with author-turned-filmmaker Bret Easton Ellis.
