Kinney and Gaga, 32, called off their engagement in July 2016 after the actor proposed on Valentine’s Day 2015. They had been together for five years.

Kinney remains a major supporter of the star and said he wasn’t surprised that she was earning praise for her first-ever major acting performance.

“No, there was no glass ceiling. Ever! She’s always inspiring and I really do – I hope it does really well, and I know it’ll mean the world to her that I think everybody is receptive and yeah, I wish her the best,” he told Entertainment Tonight.

Gaga has been dating CAA talent agent Christian Carino since Jan. 2017.
