Lindsay Lohan will appear in Lady Gaga's next video.

The controversial actress is set to star in the promo after with her new friend Gaga, who she spent time with at the Chateau Marmont hotel in Hollywood recently.

A source told the New York Post newspaper: "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."

Although she will reportedly appear in a video, it is not known what song it will be for, or when, as Gaga has only just revealed the title of the album, 'ARTPOP', and little else.

However, insiders think the project will be great exposure for Lindsay's career, which has stalled after she ran into legal problems for being caught driving under the influence (DUI) in 2007, which snowballed and eventually saw her jailed, placed under house arrest and undertake community service.

The source added: "Due to Gaga's superstar status, this would be Lindsay's biggest role by far in many, many years."

Since staging her comeback this year, Lindsay has filmed in TV movie 'Liz & Dick' - about the romance between Elizabeth Taylor and Richard Burton - and starred opposite porn star James Deen in 'The Canyons', but she has not broken back into mainstream Hollywood.

Gaga recently finished filming her first ever film role, in Robert Rodriguez's new film 'Machete Kills'.
