Jason Biggs and Jenny Mollen are Expecting Baby #2

Actor Jason Biggs and his wife (and must-follow Instagrammer) Jenny Mollen are expecting baby number two.

The quirky, hilarious couple announced the pregnancy in a totally on-brand Instagram post:

The new addition will join adorable big brother Sid, plus the couple's much-photographed dog Gina.

Now that Gina is back in LA, she decided it was time to update her headshots. #ginagirl #9isthenew2 #dogsofinstagram #JasonsEx #LosAngeles
