Jennifer Garner attended the Roundabout Theatre Company's 2015 Spring Gala honoring Helen Mirren last night in New York City, and the actress looked amazing in a simple black dress and heels. She was joined by Alec Baldwin and his pregnant wife Hilaria, who showed off her growing baby bump in a skintight red number.

The bash was titled "There is Nothing Like A Dame," and Garner was the lucky one who presented Mirren with the Jason Robards Award For Excellence In Theater. That would explain why she was extra dolled up, but where was her hubby Ben Affleck? She can't possibly have left him behind in Los Angeles to watch after their three kids, right?

Other celebs at the event included Liam Neeson, Victor Garber, Matthew Broderick, Alan Cumming and Jane Krakowski ... check out more photos in the gallery below!
