Lady Gaga casts best pal Lindsay Lohan in new music video

Just days after Lady Gaga announced her third album title ARTPOP, the 26-year-old 'Born This Way' singer has reportedly cast new best pal Lindsay Lohan in a music video.

"Lady Gaga and Lindsay caused a stir last month when they had their 'sleepover' at the Chateau [Marmont]," an insider told the New York Post.

"And now it turns out that Lindsay will be starring in Gaga's new video from her upcoming album."

While neither will confirm the rumour, Gaga and Lilo are definitely on chummy terms. Gaga posted pictures of their Hollywood slumber party last month on her Little Monsters website (see above pic).

Gaga's high-production-value video clips could be just the avenue for Lilo to claw back her credibility after years of run-ins with the law and personal troubles.

"Due to Gaga's superstar status, this would be Lindsay's biggest [role] by far in many, many years," the insider said.

Lindsay continues to claw back her career after filming the Elizabeth Taylor telemovie Liz and Dick back-to-back with her current project, a sex-scene-packed drama with porn star James Deen,The Canyons.

"Liga" or "Lalo" have another link to bond over. Gaga just filmed her acting debut in Robert Rodriguez's Machete Kills the sequel to Machete, the 2010 flick in which her bestie Lilo went topless.

Gaga's no stranger to baring all herself, as these nude moments demonstrate:
