The expecting star also posted a makeup-free selfie on Instagram, showing off her killer blue eyes and adorable freckles.
"At the spa for a pregnancy massage taking a selfie for @CancerandCareers @QVC #BeautywithBenefits," she captioned the cute candid.
The 28-year-old revealed in December that she was expecting a baby girl, making the exciting announcement right before her son's 4th birthday.
Back in November, the "Girls Next Door" alum admitted that this pregnancy is going much more smoothly than her first one.
"It's easier on the mind, I think, right now," she told E! News. "There was so much going on at the time being pregnant with No. 1. This time we have a home, we're settled, we're married, we get to plan."
