Lupita Nyong'o and Janelle Monae were all over each other at the Met Gala and raised some eye brows. Tessa Thompson was in attendance, but definitely not with Janelle (and is rumored to be dating Brie Larson?). Lupita and Janelle have been friends for years- Janelle came out as pansexual last year, while Lupita hasn't talked much about her dating life.
This is old news by now, but OP needs to know if any commenters have more dirt
