This year marks the 25th anniversary of the LBGT-friendly downtown culture and fashion rag PAPER Magazine, and the occasion will be celebrated with quite an extravagant gala at the New York Public Library. The magazine that helped make candid party snaps en vouge will be providing plenty of back-of-the-book spread fodder of its own with an invite-only guest list full of fabulous luminaries and art-world A-listers. The eclectic entertainment includes Andrew DK, British DJ Mark Ronson, pretty-boy indie-rockers the Virgins and rap queen Queen Latifah. But the evening’s true star attraction will be Liza Minnelli, who will take a break from mourning the death of her best bud Michael Jackson for a rare NYC performance — and all that jazz.
