Kanye West — who scored an invite for his pregnant girlfriend Kim Kardashian to this year’s Met Ball — may have worn out his welcome at the gala after a confusing performance of “screeching” for the punk-themed event. Sources told us West, who’s been living in Paris while working on an album that’s due out this summer, annoyed organizers by performing new music unfamiliar to the audience rather than a set of well-known hits that was prearranged. After Debbie Harry and Blondie played, loose cannon Kanye appeared in a studded, bejeweled mask and “started screaming,” spies said. “He played all new tracks that no one knew from his new album, and none of the crowd favorites,” a source said. “His songs were basically screeching into the microphone.” Another source sniffed, “Every minute of that gala is programmed, and Kanye went off-program and played whatever he wanted.” (Wait, isn’t that the punk ethos?) A Metropolitan Museum of Art rep said: “We were thrilled to have Kanye perform.” A rep for the evening’s host Vogue said they agreed.
