Brooklyn's 99th precinct is about to expand by one!

Stephanie Beatriz, who plays Detective Rosa Diaz on Brooklyn Nine-Nine, tells PEOPLE in this week's issue, "I'm pregnant!" This will be the first child for Beatriz and husband Brad Hoss.

Life has changed a lot for Beatriz, 40, these last few years. The actress, who came out as bisexual when she was college, didn't use to see herself as the type to settle down with a husband and child.
