Lake Bell and Scott Campbell were married Saturday evening at The Marigny Opera House in New Orleans, PEOPLE has learned exclusively.

The actress, 34, wore a custom-designed Marchesa Couture gown and was escorted down the aisle by her father, Harvey Siegel, at the non-denominational ceremony. Campbell wore Marc Jacobs.

Bell and Campbell, 36, a tattoo and fine artist, exchanged vows in front of 190 family and friends including Cameron Diaz, Eva Longoria, Kate Bosworth, Rob Corddry, Katie Aselton, Mark Duplass, Malcolm Gladwell, Lindsay Sloane, Erinn Hayes, Tig Notaro, Fred Melamed and Rob Huebel.

The couple met in 2011 on the set of Bell's HBO show How To Make it in America (Campbell played himself), and got engaged on her birthday in March 2012.

This is the first marriage for both Campbell and Bell, who wrote, directed and stars in the film In A World, due in theaters Aug. 9.
