Lady Gaga was in the Christmas spirit at Z100’s annual Jingle Ball concert, but her version of “White Christmas” would have made Bing Crosby blush.

Gaga performed a slightly naughty rendition of the holiday classic Friday night as part of her mini-concert at the radio station’s event at Madison Square Garden. Gaga — sporting tight studded leather pants, bare midriff and a matching top — gyrated on a set that included antlers, Christmas trees and holiday lights.

She also performed hits like “Born This Way” and “Telephone,” and remarked how as a young girl growing up in New York City, Jingle Ball was her first concert.

The concert also included performances from Kelly Clarkson, Demi Lovato, LMFAO, Pitbull and more.
