The intimate gathering was held under a tent in the yard of Facebook chief operating officer Sheryl Sandberg on Sunday night. Gaga wore a black, sleeveless gown and high heels, and with her hair piled up she towered over the Silicon Valley elites who were paying up to $35,800 per couple to attend.

Gaga attended as a paying guest. She said last week that she wanted to meet with Obama to discuss her concerns about bullying, but it wasn’t clear whether the two would be having that discussion.
