They were attending record executive Clive Davis' pre-Grammy party at a Beverly Hills hotel, when they got into a disagreement over how to perform GOLD DIGGER.
An eyewitness tells American publication Us Weekly, "Kanye didn't agree with Jamie on how he wanted to do it (perform the song).
"Kanye walked out of the party, but returned after 15 minutes, out of respect for Clive."
The duo ended up performing together at the party and after the song finished Foxx was seen hugging rappers Snoop Dogg and Ludacris, who also performed with him that night, but noticeably snubbed West, who stormed off the stage and left the party.
Foxx and West teamed up again the following night to perform the song, this time dressed as marching band leaders who were joined by drummers, a bass section and chanting cheerleaders.
