As is usually the case with rapper-on-rapper beef, the saga of Kanye West vs. Wiz Khalifa continues, with Wiz taking an added shot during a show in Argentina Wednesday night (Jan. 27).

While it may have seemed like Wiz wasn't all that interested in getting involved in the feud based on the number of tweets he sent back to Kanye during their Twitter war yesterday, the Pittsburgh rapper dropped a new ad-lib into his rendition of "Taylor Gang" last night. In footage acquired by TMZ, Wiz is shown delivering a rousing rendition of the Cabin Fever track and drops a not so subtle "Fuck Kanye" in toward end.

Twitter and the collective rap consciousness erupted yesterday when Kanye let a flurry of tweets go directed at Wiz in response to Wiz's criticism of Kanye changing his album title to Waves. The crux of the beef could be interpreted as Wiz's Waves comments, but truthfully, there has been tension under the surface for quite some time. Kanye had made a comment to The Breakfast Club in Feb. 2015 that Kim Kardashian made him take 30 showers because of his relationship with Amber Rose, someone who Wiz had later married and had a child with.

Kanye referenced Wiz and Amber's relationship on 2012's "Cold," rapping, "And the whole industry want to fuck your old chick/Only nigga I got respect for is Wiz." While Kanye may have been complimentary to Wiz in the past, he insulted the rapper and his family on Wednesday tweeting, "You wouldn't have a child if it wasn't for me."

Dissing people on stage is nothing new in rap, as just last October, Meek Mill addressed his beef with Drake while on stage at Powerhouse Philly. We will continue to update the Wiz-Kanye story, though Kanye told reporters yesterday that he is through speaking on the subject.
