She's probably just looking right to make sure she wasn't late for the premiere. I doubt that was her intention at all.
But she also drops her arms to her sides, and to me her body language just says "I'm done with this interview". I might be wrong though, it just came across a little weird is all.
Sorry, she didn't seem rude at all to me. She was probably just a bit tired from doing interviews all day. She obviously walked away like that to make the answer seem more dramatic. The REACH for a hit thread.
She HONESTLY looked kinda irritated for whatever reason. I'm guessing long day and she was tired. That said, she seemed to be trying to act professional and I totally get an off day.
I absolutely love Gaga as a person too. I think she is incredibly sweet
