La La (Ashlee Simpson song)

"La La" is a song by American singer Ashlee Simpson from her debut album, Autobiography (2004). Two weeks after it became available as a digital download in mid-August 2004, it rose to No. 37 on Billboard's Hot Digital Tracks. In the U.S., it began its run as the album's third and final single on radio and television in November 2004; in the United Kingdom, where it was the second single, a CD single was released in January 2005. The song's video was in heavy rotation on MTV by December 2004. In March 2005 the single was certified Gold, and in August the video was nominated for Best Pop Video on the MTV Video Music Awards.

Simpson performed "La La" multiple times on television in 2004. On January 4, 2005, Simpson performed the song live at the halftime show of the Orange Bowl football game in Miami, Florida. She sang off-key, and after singing the last line, the stadium audience booed her. Critics compared this poor performance to Simpson's revealing miscue on Saturday Night Live October 23, 2004, in which she had intended to perform "Autobiography" but the earlier recording of "Pieces of Me" was heard instead, showing that Simpson had been lip-syncing. Simpson explained the poor performance of "La La" was the result of an equipment failure, with her in-ear monitors not working.
