Lindsay Lohan Spend Time with Another Sam

Matt Donnelly / March 22, 2009

Lindsay Lohan traded a DJ for a singer on Saturday night, although both were named Sam.

Lilo took in an after-hours performance of singer Sam Sparro last night in Los Angeles, at Hollywood hotspot Bardot.

Arriving close to 1 a.m., Lohan rolled into the “Black and Gold,” singer’s intimate performance clad in black leggings (naturally) and a black top with a jeweled neckline.

“She looked gorgeous,” an onlooker tells Celebuzz, “really thin but pretty. She had great energy.”

Lindsay rocked out enthusiastically to the gay, Grammy-nominated vocalist, occasionally taking photos with her Blackberry.

After Sparro’s six-song set, Lohan fetched a faded white t-shirt from her Chanel purse and ran to the bathroom, telling friends she was hot, according to our source.

She returned soon after (accessorizing the shirt with a black shoestring belt) and chatted up Sparro and his band.

“Lindsay was clearly impressed, ” the partygoer said, “she took everyone’s number and stayed to chat and dance.”

Absent was Lohan’s mainstay gal pal Samantha Ronson.
