Lake Bell made a big announcement at Vanity Fair’s Tribeca Film Festival party: She’s pregnant.

Bell, 35, showed up for the event at the State Supreme Courthouse in New York on Wednesday alongside tattoo artist husband Scott Campbell, 36.

The “In a World …” star showed off her new baby bump in a Stella McCartney jumpsuit.

Bell and Cambell were married last June in New Orleans.

The announcement comes just after the actress appeared in a sexy cover shoot for Esquire magazine.

Bell’s next movie, “Million Dollar Arm” opens on May 15.
