Lindsay Lohan starring in Lady Gaga's new music video?

lindsay-lohan-lady-gaga-pics-music-video-rumor-gi.jpg Lady Gaga posted pics on her social networking site LittleMonsters.com of her and new pal Lindsay Lohan slumber partying it up in July at the Chateau Marmont, and now rumors are swirling that the two will be pairing up again -- this time professionally.

"It turns out that Lindsay will be starring in Gaga's new video from her upcoming album," a source tells the New York Post. "Due to Gaga's superstar status, this would be Lindsay's biggest [role] by far in many, many years."

Gaga recently wrapped work on her own acting role in Robert Rodriguez's "Machete Kills" and has just started releasing details about her upcoming album "ARTPOP." She tweeted out a pic of her new tattoo -- the word "ARTPOP" in simple black lettering on her arm -- along with the caption, "new ink new album" to fans on Friday (Aug. 3). And in July she blasted a new song on the streets of New York.

As for whether Lohan will be part of Gaga's "ARTPOP" movement, we'll have to wait and see.

A source close to Gaga tells the Post, "Lady Gaga's not shooting a music video at this time."

Reps for Gaga and Lohan declined to comment.
