Eminem has never been one to shy away from controversy. Known for his unapologetic lyrics and sharp-tongued diss tracks, the Detroit rapper has made enemies across music, Hollywood, and even politics. Whether personal or professional, his feuds have often played out publicly—sometimes explosively.

Here’s a rundown of some of the most high-profile celebrities who have had open beefs with Eminem over the years:

1. Mariah Carey

Perhaps the most famous and long-running feud on this list, the tension between Eminem and Mariah Carey began in the early 2000s after Eminem claimed they had dated—something Mariah consistently denied. In response, Eminem dissed her in multiple tracks, most notably “Superman” and “Bagpipes from Baghdad.” Mariah fired back with the song “Obsessed,” and Em replied with “The Warning”, a brutal diss track that included voicemails and personal details.

“Only reason I dissed you in the first place is ’cause you denied seeing me. Now I’m pissed off.” – “The Warning”

2. Nick Cannon

As Mariah’s ex-husband, Nick Cannon naturally got pulled into the drama. Over the years, he and Eminem traded insults in songs, interviews, and social media posts. Nick released multiple diss tracks targeting Eminem, including “The Invitation” and “Pray for Him”, though critics widely considered Eminem the winner of the feud—even though he barely responded.

3. Machine Gun Kelly (MGK)

This modern-day rap beef made headlines in 2018 after MGK called out Eminem’s daughter Hailie in a 2012 tweet. Years later, Eminem dissed MGK on “Not Alike”, prompting MGK to fire back with “Rap Devil”, a surprisingly strong response. Eminem ended the exchange with “Killshot”, which became one of YouTube’s most-viewed diss tracks. The feud arguably reshaped MGK’s career, pushing him away from rap and into pop-punk.

4. Christina Aguilera

Eminem dissed Aguilera in “The Real Slim Shady”, accusing her of revealing personal details about his life. Christina, in turn, criticized his lyrics and behavior in interviews. Though not as intense as some of his other feuds, the beef added to Eminem’s image as someone unafraid to take on pop stars.

5. Moby

The electronic music pioneer criticized Eminem for his violent and misogynistic lyrics, calling him a bad influence. Eminem clapped back in songs like “Without Me” where he called Moby out directly:

“Nobody listens to techno! Now let’s go.”
Moby later said he wasn’t offended, but the public spat showcased Em’s sensitivity to criticism from the music industry.

6. Benzino

Former co-owner of The Source magazine, Benzino launched a campaign to discredit Eminem’s credibility and cultural place in hip-hop. This sparked a full-blown war, with Eminem releasing scathing diss tracks like “The Sauce” and “Nail in the Coffin.” The beef significantly damaged Benzino’s reputation and helped solidify Eminem’s dominance in rap.

7. Ja Rule

As part of the larger feud between 50 Cent and Murder Inc., Eminem joined the war and took shots at Ja Rule after he mentioned Em’s daughter Hailie in a diss. Eminem’s response was fierce, with songs like “Hailie’s Revenge”, where he rapped alongside his daughter. The public overwhelmingly sided with Eminem and 50 Cent in this feud.

8. Everlast (of House of Pain)

This lesser-known beef started when Everlast claimed Eminem snubbed him backstage. Diss tracks were exchanged—Everlast dropped “Whitey’s Revenge”, and Em responded with “I Remember” and “Quitter”. It was a short-lived feud, but memorable for fans of early-2000s diss culture.

9. Will Smith

While not a full-blown feud, Eminem did take shots at Will Smith in “The Real Slim Shady” for saying he didn’t need to curse in his music to sell records. Em rapped:

“Will Smith don’t gotta cuss in his raps to sell records / Well I do / So f*** him and f*** you too.”
The jab wasn’t personal—more a critique of industry standards—but it still stirred media attention.

10. Canibus

In the early 2000s, Canibus accused Eminem of ghostwriting for LL Cool J—something Em denied. The two traded multiple diss tracks, but the conflict never fully escalated to the heights of some of Em’s other rivalries.

No One Is Off-Limits

Eminem has never been afraid to name names, call people out, or defend himself when provoked. Whether justified or not, his feuds have often made for compelling music and unforgettable moments in pop culture. Some have fizzled out, others have turned into legends—but through it all, Eminem has proven one thing: if you come for him, you better be ready for lyrical war.
