The 35-year-old actress has been keeping her baby bump a secret until she debuted her belly to the world Wednesday evening, stepping out at the Vanity Fair party at the Tribeca Film Festival in New York. 

Donning a tight burgundy jumpsuit, the actress glowed as she cradled her growing bump, along with a chic snakeskin purse and sky-high Christian Louboutin pumps. 

This will be the first child for the couple, who met on the set of How to Make It in America back in 2011. Bell and Campbell were married last June in New Orleans.
