She's a force of nature. Have you seen those arms?! No doubt her legs are just as strong. She looks extremely physically fit. It's no surprise that she has the stamina to do this but no less impressive.
To run a marathon and then sing and act that role twice is beyond anyone on this earth to do. Her stamina is ****ing unreal and her talent and devotion to her work exceeds expectations. You make them right London, keep doing that.
Also, Dear Cynthia's Mom- Thank you for contributing to the most beautiful, talented, sweetest creature to ever step foot on a Broadway stage.
I was on instagram when she posted that pic and my first thought was, without any doubt, that she wouldn't be taking any breaks and would performing two shows that day, because that's just the kind of powerful and brilliant person she is. Superwoman.
