9 Pop Stars Who Wrote Songs About Other Celebrities — & They Weren't Always Singing Their Praises

Gomez admitted to On Air With Ryan Seacrest that Bieber is the subject of the song, but that he thought the song was “beautiful,” despite its not-super-flattering depiction of their tumultuous relationship.

The songstress has written about a whole lotta celebrities, but she made headlines for allegedly calling out this catty pop star.

Rumor has it that Swift’s song “Bad Blood” off of her 2014 album 1989 is about her feud with Perry.

Timberlake allegedly wrote this tune after he was cheated on by his famous girlfriend.

They may have been the ultimate 90s pop star couple, but after Spears and Timberlake ended things, Timberlake wrote the bitter breakup tune “Cry Me A River.”

Though there’s some speculation as to whether this sitcom star is truly the subject of the song, even he admits that some of the lines hit particularly close to home.

The Full House star isn’t sure that his ex-girlfriend Morisette’s angry breakup tune “You Oughta Know” is about him, but he did admit that some of the lines in her song do reference specific moments in their relationship.

The “No Doubt” singer was inspired by this celebrity’s remark when searching for a inspiration for a new single.

The Hole singer inspired Stefani’s anthem “HollaBack Girl” when she called Stefani a “cheerleader” and not a “rock star” in an interview. (I know, I know — this shit is bananas.)

The “Jealous” singer wrote this tune about his first love.

Jonas wrote the song “Wedding Bells,” which is about an ex who is getting married, in response to Cyrus’ engagement to Liam Hemsworth.

Perry allegedly wrote this harsh song about her ex-boyfriend.

Perry allegedly called out ex-boyfriend McCoy, who entered rehab for a drug addiction in 2008, in her song “Circle The Drain.” One particularly telling line was “you fall asleep during foreplay/’cause the pills you take are more your forte.” McCoy responded to the diss by saying he was glad she wrote a song with substance.

The “Body Is A Wonderland” singer allegedly wrote this song in response to one his ex wrote about him.

The tables turned on Swift — who allegedly penned the not-so-complimentary “Dear John” about Mayer — when Mayer released the song “Paper Doll.” It referenced Swift’s hit single “22” by saying that she’s “like 22 girls in one.”

The late Winehouse penned this track about a hip hop star that you totally didn’t know the last name of until now.

Nas — real name Nasir Jones — was the inspiration for Winehouse’s song “Me and Mr. Jones,” which drops plenty of references to the artist. The two artists were friends, and, as the song suggests, may have been something a little bit more.
