• In this saucy song, Ashlee Simpson has herself a man who makes her want to "la la," a pretty obvious stand-in for sex. She'll be happy to dress up like a French maid, let him throw her around like a lineman, and get busy on an airplane. Ashlee was only 19 at the time and many of her fans were considerably younger, so we'll hope lines like this went over their heads:
  
  I'm like an alley cat
  Drink the milk up, I want more
• Simpson performed "La La" as part of the halftime show at the 2005 Orange Bowl a few months after her Saturday Night Live appearance where she was caught lip-synching. Simpson was roundly booed when she finished, and the incident was captured as part of the MTV series Newlyweds, which followed the exploits of Ashlee's sister Jessica and her husband Nick Lachey. Lachey was a huge fan of USC, who was playing in the game, and cheered wildly during the game while Jessica seemed disinterested. At halftime, Jessica focused her attention on her sister's performance. She thought Ashlee sounded great (the Songfacts staff strongly disagrees) but couldn't understand why the crowd was booing. Lachey tried to comfort her by saying the crowd was there to see football.
• Joseph Kahn directed the music video, which follows Simpson's adventures throughout Huntington Beach, California. She dances on top of a car, plays Xbox, party's 'til the cops come, and causes a ruckus at a laundromat. She likens the video to the 1982 teen flick Fast Times at Ridgemont High (though none of these events occur in the movie). The making of the video was featured on The Ashlee Simpson Show and on MTV's Making the Video.
  
  Kahn is known for directing a slew of artists, including other pop singers like Britney Spears ("Toxic"), Kelly Clarkson ("Behind These Hazel Eyes"), Katy Perry ("Waking Up In Vegas"), Lady Gaga ("LoveGame"), and Taylor Swift ("Blank Space").
• Simpson wrote this song with Kara DioGuardi and John Shanks, her main collaborators on her first two albums (Shanks was also the producer). It was released as the third single from her debut album, Autobiography.
  
  "I remember being at Henson Studios, and me and Kara were like, 'John, leave us alone,'" Simpson told the LA Times regarding the writing process. "We went out back and put boas on and we had our moment. Kara was like a big sister to me - really helping me find myself and listening to me. She made me feel safe, but she also let the beast out. And she trusted the beast."
