Madonna and Lady Gaga at 'The Party'

What happens when two boundary-pushing pop queens of different generations come together in one photo? Twitter freaks out, naturally.

That's what happened on Monday morning when a photo from Guy Oseary and Madonna's annual Oscars after-party, 'The Party,' from Sunday night started to circulate on social media. The photo in question, taken by photographer JR, comes from the party's photo booth, which had a background made from crumpled white paper, and shows Madonna embracing Lady Gaga, who is holding her newly-won Academy Award.

Because the party has a strict no social media rule, fans didn't even know that Gaga had attended Madonna's star-studded affair. The 'A Star Is Born' actress wore her second all-black look of the evening, with her hair in an Old Hollywood-style updo. Madonna opted for an off-white satin garment that she donned with a lavish gold-and-diamond headpiece and tons of other jewelry.
