Kanye West is a heavyweight champ when it comes to celebrity feuds. Over the years, the rapper, 38, has gone toe to toe with numerous musicians, models and TV hosts and even American presidents — taking to Twitter, the stage and/or live to call them out on their latest offenses.

After West’s latest online scuffle with Deadmau5 began on March 1, we thought it was time to take a look back at the artist’s most famous battles.

Who can forget the 2009 MTV Video Music Awards—the place where West and Taylor Swift’s complicated relationship began? West surprised everyone by taking the stage as Swift accepted her award for Best Female Video. His interruption, “Yo, Taylor, I'm really happy for you, and I’mma let you finish,” launched a million memes that still reverberate around the Internet over 6 years later.

Since then, West has been putting on his boxing gloves to throw right hooks at fellow celebs on a regular basis.
