Kanye West is a class act.  While onstage at the Coachella Music Festival last weekend, West made a few tweaks to his “Stronger” lyrics: “I did anything for that blond d**e/ And she did anything when the time’s right,” West sang, obviously making a dig at his ex-girlfriend, Amber Rose.

Rose was in the crowd when West sang those updated lyrics, and Rose’s new boyfriend Wiz Khalifa had a few words for him backstage after West finished his set.  A source said that Khalifa didn’t want to fight, but he did want to end “all this catty buls**t.”  Naturally, West didn’t take kindly to what Khalifa had to say and things got heated.  Says a source, “Kanye said something to Wiz and next thing you know security and people’s entourages were everywhere pushing and shoving. It could have got real ugly.”

West was taken away by security, but the scuffle didn’t seem to ruffle Khalifa’s feathers.  He tweeted Sunday, “”been waken…baken…and all that s**t. tweetin from a 48 inch television. f**k iz up?” Rose and Khalifa spent some time snorkeling in Barbados last week.  Not one to miss a photo op, Rose posed in her bikini and life jacket for the cameras.  Again, classy.
