Jessica Simpson dressed as a mummy on Halloween to announce her first pregnancy. Jenni 'JWoww' Farley chose a different holiday: Christmas.

Snooki's BFF, 27, posted a Christmas card on herblog featuring an ultrasound picture of her bun (panettone?) in the oven.

"We couldn't have wished for a better gift this Christmas!" reads the card. "Happy holidays from our growing family to yours! Love, Jenni, Roger and arriving July 2014 Baby Mathews."

Roger, of course, is the former Jersey Shore star's longtime boyfriend and current fiance.
