Set AITA for telling other actors on set what I was getting paid?

OK so this might be controversial. I was on a micro drama shoot, 8-day booking, supporting role. During lunch on day 3, another supporting actor mentioned she was getting $350/day. I was getting $550/day for basically the same amount of screen time and lines. I told her my rate. She was pissed — not at me, at the production. She went to the producer and apparently there was a whole thing. The producer pulled me aside the next day and said I "created an uncomfortable situation" by sharing my rate and that it was "confidential information per the deal memo." I checked my deal memo. There's no confidentiality clause about rates. And even if there was — shouldn't actors know if they're being paid less for the same work? The other actress thanked me. The producer is pissed. A few people on set think I stirred up drama for no reason. AITA?
