The hint may have gave it away because the answer is in fact Catherine Zeta-Jones. Zeta-Jones was also spotted on the set of The Bitter Pill in NYC on May 19.
After being married, having 2 kids and getting older it doesn’t look like she has aged a bit. I’m so jealous of how beautiful she still is. Not only was Jude Law working with Zeta-Jones on this scene, but he was also seen on set earlier in the day.
