I want to know the answer to the following question:
What artist did Kanye West have a feud with over Amber Rose?
All the background I'm provided with is that "He announced in January 2016 on Twitter that SWISH would be released on February 11, after releasing new song "Real Friends" and a snippet of "No More Parties in L.A." with Kendrick Lamar.". Is that enough to answer the question?
