Lindsay Lohan Reveals The Secret Of Her 'First' Video

Third Speak clip ties in to her latest big-screen project.

Consider Lindsay Lohan's crossover from cute Disney starlet to full-blown rock chick nearly complete.

The actress is barely recognizable in the video for "First," the third single off her platinum debut, Speak. Ditching her trademark red hair and buxom curves, Lohan shows off her new, über-svelte physique — and blonde locks — for the single, which is also being used to promote her race car flick, "Herbie: Fully Loaded," hitting theaters June 22.

"First" was directed by Jake Nava, who also did Lohan's "Rumors" and "Over." "I actually just saw the video recently and I was really happy with [how it turned out]," Lohan said. "Jake did an amazing job, and we had a great team there."

The premise revolves around Herbie, the magical Volkswagen Bug that helps Lohan's character pursue her NASCAR dreams (see "Lindsay Lohan: Bug Possession"). The singer, donning some aviator shades, rocks out with her band on top of a checkerboard stage, amidst a whirlwind of flashy race cars and leather-jacket-clad hotties.

"We actually got the race cars from '2 Fast 2 Furious,' " she said. "There's a lot of racing going on and there's a secret behind the [plot], because Herbie comes out in the middle of the video and ends up winning the race."

Lohan unveils herself at the end as the hotshot victor behind the wheel.

The 18-year-old — who recently also finished filming the comedy "Just My Luck" (see "Lindsay Lohan Pushes Her 'Luck' ") — is refocusing on music, developing songs for her sophomore LP, which she hopes to start recording by late fall.

"I've been writing a lot, almost every night," she said. "There's been a lot going on [in my life lately], and I think people can find that escape in hobbies that they do. I don't do yoga or anything, but some people use that. Everyone has their own thing, and I use writing."

Lohan has been a tabloid staple due to speculation about her dramatic weight loss and alleged hard-partying lifestyle, so she should have no trouble kicking out some angst-ridden rock anthems.

"When you get into the studio, everything just comes out," she said. "All your creative juices are there. I don't [want to] leave. I'll still be in there until all hours, and it's nice to be able to do that."

Next up for Lohan moviewise is the romantic comedy "Fashionistas," based on Lynn Messina's novel about a young fashion-magazine assistant who schemes against her demanding boss. Then the young actress will team up with some acting heavyweights in "A Prairie Home Companion," also featuring Woody Harrelson, Lily Tomlin and Meryl Streep. The film, which will be released next year, tracks the fictional demise of the popular radio program hosted by Garrison Keillor.
