Kanye West Performs at Sweet 16

Kanye West made a surprise guest appearance at artist friend George Condo's daughter's sweet sixteen over the weekend.

According to perezhilton.com, Mr. West performed at the party, which was held at the Standard Hotel in Manhattan last Saturday night (January 29).

Condo, whose paintings are currently on display at NYC's New Museum, designed the controversial cover art for West's last disc My Beautiful Dark Twisted Fantasy.

As previously reported, Condo told New York magazine that Yeezy specifically asked for the illustration to get him in hot water. —Elan Mancini
