Lindsay Lohan's BFF Weekend with Samantha Ronson

Girls just wanna have fun – and Lindsay Lohan is no exception.

The 21-year-old actress – who was sued last week by a former bodyguard – spent the weekend hitting the hottest clubs in L.A. with her good pal, DJ Samantha Ronson.

The duo got a jumpstart on the weekend Thursday night, when they hit the upstairs VIP area of Goa. Lohan (who has said she's "back on track" after her stints in rehab) bopped to the music as Ronson spun in the DJ booth. "Lohan was obviously having a good time, dancing very sexy," says an onlooker. "She was quite the center of attention."

The next night, it was all about Foxtail: Lohan sat at a table near the dance floor nursing a bottle of Voss water while Ronson worked the room saying hello to friends. Later, they snuck a few cigarettes at their indoor table.

And finally, to round out their weekend, they hit Teddy's at the Hollywood Roosevelt Hotel on Saturday.

Ronson headed back to the DJ booth while Lohan – in a black tank dress and black boots – chatted with friends at a nearby table. The actress kept things low-key, but perked up noticeably when Ronson spun Madonna and Justin Timberlake's new single, "4 Minutes." Later, during Mariah Carey's "Touch My Body," Ronson threw her arms around Lohan as the two moved to the music.
