The 'Only Murders in the Building' co-stars sparked much fan speculation about them possibly being a couple when they were seated next to each other at the 'SNL50' anniversary special.

During Friday’s SNL50 concert, the camera panned to Streep and Short while former SNL cast members Will Ferrell and Ana Gasteyer were on stage reprising their characters Marty and Bobbi Mohan-Culp. Streep jokingly flipped the bird at the comedians while Short laughed along.

Streep attended the concert at Radio City Hall in New York City with her rumored boyfriend, Only Murders in the Building costar Martin Short. The pair were shown on camera several times throughout the televised event. But there was one unforgettable moment during the broadcast, during which Streep gave her middle finger to the camera.
