Actress Lake Bell is pregnant with her first child.

The It's Complicated star, who is married to tattoo artist Scott Campbell, showed off her growing baby bump for the first time at a Tribeca Film Festival Vanity Fair party in New York City on Wednesday night (23Apr14).

The mum-to-be wore a form-fitting maroon jumpsuit and appeared to confirm the happy news by cradling her belly as she posed for photographers.

The big reveal comes just weeks after Bell posed for a sexy Esquire magazine photoshoot.

Bell and Campbell wed last year (13) in New Orleans, Louisiana.
