Lindsay Lohan and Samantha Ronson Shack Up in Chicago

Lindsay Lohan joined her gal pal Samantha Ronson this weekend in Chicago, where the lanky DJ performed at Crimson Lounge Friday night and Hard Rock Hotel on Saturday.

Although Ronson came to Chicago for work, she also made time for fun.

A source at the hotel confirmed to CelebTV.com that Ronson and Lohan were sharing the Chairman’s Suite at The Hotel Sax Chicago.

The swanky suite, where the pair stayed for two nights, costs $5,000 a night and is decked out with four TVs, an X-box and a computer station.

An insider tells CelebTV.com that Ronson requested to have the game Rock Band–one of her favorites–brought up to the room.

Ronson arrived at Crimson Lounge Friday night and started spinning around 11 p.m. Dressed in a gray sweatshirt and her signature fedora, Lohan’s short-haired sidekick smoked cigarettes and drank Red Bull mixed with alcohol until the actress arrived. She played everything from modern hits by Kanye West to older tunes like Smokey Robinson’s Tears of a Clown.

Lohan arrived 45 minutes later, wearing a white tank top with her hair pulled back. The 22-year-old actress sat in the DJ booth with Ronson. Sources told CelebTV.com that the two were “affectionate,” even putting their arms around each other.

When Ronson finished her set, the duo went to Chicago hot spot Underground around 2:45 a.m. to watch Ronson’s brother, Mark, spin with Danny Masterson.

Lohan also supported her music-making friend Saturday night, when the DJ performed at Hard Rock Hotel for the Metromix.com’s Rock the Vote Nights at The Music Lounge.

Lohan’s rep has said the actress and Ronson are “very close friends,” but has given no official word yet on whether the two are officially together.
