Taken by Rhonda Dent, the picture shows Vanessa's husband Nick Lachey crouching down to kiss his wife's pregnant belly while holding the couple's son, Camden, on his shoulders. Camden, 2, is cupping his mom's face in his little hands and giving her a sweet peck on the lips, while Vanessa holds onto his tiny feet.
"Today I wanted to wish you a Happy Holiday from my family to yours, and share our 2014 Lachey family Christmas card," she wrote on her website. "This photo was taken on Camden's birthday and it's my favorite picture of all four of us...at least, so far!"
No doubt there are more cute pictures to come — especially once the TV host, 34, gives birth to her second child, a baby girl. She and her ex-boy bander hubby announced they were expecting this past July.
The mom-to-be teased another big announcement on her blog on Dec. 23, telling readers to check back in a few weeks for the news. "You can expect lots of fun stuff to come in the New Year right here on my site," she wrote. "Let's just say it's one of my biggest resolutions for 2015!"
