Lady Gaga attended the 13th "Backstage at the Geffen" fundraiser on Saturday night to support her friend Elton John, who was among the honorees at the annual event.

Gaga, who is the godmother of Elton and his husband David Furnish's sons, Elijah and Zachary, sang her hit single "Yoü And I," changing some of its lyrics to fit the occasion.

"Honoring Elton and David for a Distinction in Theatre," Mother Monster wrote on Instagram. "What a wonderful place this playhouse is, giving the possibility of 'magic,' as Elton says it, by making theatre available to more people, so no one is left behind."
