Christmas Tree (Lady Gaga Song)

"Christmas Tree" is a song by American singer Lady Gaga. It was released on December 16, 2008 for digital download. It was written and produced by Gaga, Martin Kierszenbaum, and Space Cowboy, who also provides guest vocals. Musically, "Christmas Tree" is a Christmas song with dance-pop and synthpop influences. It samples the classic Christmas song "Deck the Halls", as well as briefly using the lyrics "Rum pum pum pum" from the Christmas song "The Little Drummer Boy" in its intro. Lyrically, the song uses sexual innuendos.

The song received mixed reviews from music critics, with some commending its creativity and individuality from other Christmas songs and others criticizing its sexual innuendos and deeming it "not for the family". Due to strong digital sales, it reached number 79 on the Canadian Hot 100 chart in January 2009. It also reached number 18 on the Japanese RIAJ Digital Track Chart and number 23 on the Billboard Holiday/Seasonal Digital Songs chart in the United States in late 2010. In December 2009, it was available for free download on Amazon as part of the site's "25 Days of Free" promotion. The song has been included in several Christmas compilation albums, including ''Now That's What I Call Christmas! 4''.
