"I Don't Want to Be Your Friend" is a pop/R&B song written and composed by Diane Warren. It was first recorded by singer Cyndi Lauper for her 1989 album A Night To Remember. The song was meant to be the second commercial single released in the U.S. from that album, but after the second radio single "A Night to Remember" failed to chart highly, the label scrapped the idea. Famed songwriter Desmond Child also recorded a version for his only album Discipline (1991). "I Don't Want to Be Your Friend" was eventually a single by Filipino singer Nina, and also recorded by Dutch female singer Do in her eponymous debut album.

"I Don't Want to Be Your Friend" was covered by Filipino singer Nina as a single from Diane Warren's 2004 love songs compilation, Diane Warren Presents Love Songs. The song was produced by Neil C. Gregorio, and published by Warner Music Philippines. It was included as a bonus track on Nina's best-selling 2005 album Nina Live!, and has since been considered as a single from that album. It later appeared on her 2008 album, Nina Sings the Hits of Diane Warren. The song talks about a woman who was left and hurt by her past lover. She admits being uncool with what happened to their relationship, expressing that "she doesn't want to be his friend".

Upon release, the song was met with positive reviews, being included by music critics as one of the favorite tracks in Nina's albums. Titik Pilipino complimented the simplicity of the song, saying "it's one song where [Nina] didn't have to shout and be a vocal Chinese acrobat." The song was nominated for Favorite Female Video on the 2005 MTV Pilipinas Music Awards, but lost the award to Rachelle Ann Go's "Love of My Life". On January 15, 2007, the song was released to digital download via iTunes and Amazon.com.
