St Vincent performed at a New York Fashion Week party at the Highline Stages last night (9/6) to help celebrate the launch of the new Tiffany & Co. fragrance, whose commercial is soundtracked by St. Vincent's cover of "All You Need Is Love." At last night's show, she was joined on stage by Doveman (aka Thomas Bartlett), who plays on her just-announced album Masseduction and whose NYC show the previous night (9/5) featured a surprise appearance by St Vincent. She played the Beatles cover, plus a few songs from earlier on in her career ("Marry Me," "The Party," and "The Bed"), "Prince Johnny" off her most recent album, and her fantastic recent single "New York" off the upcoming Masseduction. You can watch some videos from the show, including a few of her playing "All You Need Is Love," below. Pictures are in the gallery above.

St Vincent isn't the only cool musician performing at New York Fashion Week parties this year. Rihanna, Future, Nicki Minaj, The Weeknd, Cardi B, Lizzo, and more (maybe Kanye?) all have performances at upcoming events. For more info, check out our guide to music at New York Fashion Week.

St Vincent's new album will be out on October 13. In addition to "New York," it features the just-released single "Los Ageless." Her proper tour includes two shows at Brooklyn's Kings Theatre in December. She's also curating a Peroni pop-up in New York in October.
