Kanye West addressed his ongoing feud with Taylor Swift during an impromptu appearance at rapper Drake's concert.

The 39-year-old Famous rapper was a surprise guest on stage at Drake's gig in Chicago, Illinois on Wednesday (27Jul16), and he broke his silence about the dispute which saw Kanye's wife Kim Kardashian, 35, publish a video of a private phone conversation with Taylor.

Earlier this month (Jul16), Kim posted a video on her Snapchat social media account, showing her husband speaking to the Bad Blood singer about the lyrics of his track Famous.

The audio appeared to contradict a previous claim made by Taylor that she had not authorized the hip hop star to use a lyric about her which said, "For all my Southside n****s that know me best, I feel like me and Taylor might still have sex."

Addressing the Chicago crowd with a hint of a smile Kanye said, "All I gotta say is, I am so glad my wife has Snapchat, because now y'all can know the truth and can't nobody talk s**t about Ye (Kanye) no more."

The audience then chanted Kanye's name while Drake looked on with a grin.

When Famous first appeared in February (16), Taylor's representatives stated she had not given the Jesus Walks musician permission to include lyrics about her, a claim he and his wife contradicted in interviews.

In the Snapchat video of their telephone conversation Taylor can be heard saying, "Umm, yeah go with whatever line you think is better. It's obviously very tongue in cheek either way. And I really appreciate you telling me about it, that's really nice," in response to his questions over whether she would approve.

However, since the video emerged the 26-year-old star has pointed out that it did not show her authorize the next line in which Kanye rapped, "Why? I made that b**ch famous."

Coupled with the recent news that Taylor had split with her ex-boyfriend Calvin Harris and swiftly taken up with British actor Tom Hiddleston, the revelation resulted in a public backlash against the Blank Space singer.

It was speculated that Kim could face legal consequences for recording and publicizing the phone conversation as California law forbids the recording of private conversations.

However editors at TMZ.com report she may be in the clear, as the footage appears to show Taylor was aware more than one person was listening in on the call, and the law only applies to cases where an individual believes they are conversing with one other person.
