I don't think Latifah was being shady though - someone probably just grabbed her attention intentionally.
Hell, even Leo wasn't actually being shady. There were a few grumps with ugly faces in that audience though.
Latifah was laughing along with everyone when Gaga said "I wanted to act originally but music came first I guess" while looking at her friend next to her. She wasn't being shady at all.
I don't have any pictures but in the stream, you can see her genuinely smiling and looking so pleased that Lady GoldenGlobega won. She was clapping for her the entire time.
