Chrissy Teigen surprised John Legend with nakedness for Father's Day.

Chrissy Teigen is a champion of social media, but it seems she's also a champion of gift-giving. Just wait until you see what she got John Legend for Father's Day.

Legend was in Boston on Father's Day because he's performing a concert there Monday night. So, Chrissy Teigen decided to surprise him by showing up naked in his hotel room on Monday morning. Oh, she also brought him a cake.

Teigen posted a photo of her sneaky surprise to Instagram. (Don't worry, she covered herself up. With a sheet. And cake. Very classy.)
