Lindsay Lohan -- and her alcohol-monitoring ankle bracelet -- hit the clubs earlier this week.

Around 11:30 p.m. Wednesday, the newly-blonde actress, 23, arrived at Las Palmas in Hollywood. A source tells UsMagazine.com she wore bootcut jeans to hide the SCRAM bracelet. (She recently Twittered: "can CHANEL please help me out by getting me some stickers to put on my scram bracelet so that i can at least wear a chic dress?! maybe!? X")

She stayed away from booze and nursed an energy drink all night as Emile Hirsch, Adam Levine, Danny and Chris Masterson and Shane West made the club rounds.

On Thursday, posters for Lohan's upcoming Linda Lovelace biopic Inferno hit the web. In one, she is seen in her underwear laying on her back.

Lohan plays the infamous 1972 Deep Throat porn star.

No word whether her SCRAM bracelet will interfere with filming.
