It's almost time!
"Check out my cover #ilovemybump sooo close to meeting this little guy!" she wrote as the caption to the cute pic.
The E! star recently opened up about how easy things have been in her second pregnancy, and that she's had the same cravings she had when she was pregnant with her first son.
"I'm lucky. Both pregnancies have been really easy for me, I've just been really tired. It's just one of those things where I could literally sleep all day everyday but I'm snapping out of it a little bit now that I'm in the second trimester," Cavallari told us.
"I had a really heavy sugar phase there for a few weeks, and literally my husband had to cut me off of sugar because I broke out the worst I've ever broke out my entire life, so I basically poisoned myself. My body was in shock, but I had that with Camden as well."
Cavallari also explained that her firstborn may need a bit of time to transition and adjust to becoming a big brother.
"[Camden] might be a little jealous at first, but once he gets over that initial shock, he'll probably be really happy."
