Soon there will be four to celebrate! Kristin Cavallari wished her husband Jay Cutler a very happy birthday as he turned 31 on Tuesday, April 29. The Hills alum, who's expected to welcome the couple's second child any day now, did so as she shared a sweet snapshot of the twosome via Instagram.

"Happy 31st birthday to my man," the 27-year-old gushed. In the up-close photo, Cavallari leaned on the Chicago Bears quarterback as they smiled from ear-to-ear. The reality star went makeup-free as she concealed her baby bump.

Cavallari has been nothing but fashionable since announcing her second pregnancy last October. She dressed her growing belly in a nude-and-black lace mini by Balmain while attending Elton John's Audi-sponsored AIDS Foundation Oscars viewing party in West Hollywood on March 2. On April 8, she cradled her bump in a flattering white crop top placed over a nude-colored pleated dress. 

The shoe designer has clearly embraced her maternity wear. "I think just because you're a mom, it doesn't mean you have to sacrifice style. You can still be fashionable and wear what you love," Cavallari, also mom to 19-month-old son Camden told I Heart Heels recently.

"It's important to stay true to who you are. It's changed my life in a million ways for the better, but overall I just have more love and happiness in my life," she continued. "It doesn't matter how hard things get, I can always be with Camden and it instantly puts me in a good mood, and makes me remember what's important in life."
