As for the couple's wedding, it's on hold for now.

Patridge and the 34-year-old BMX biker had been dating off-and-on since 2008 -- Bohan even popped up in a few episodes of the MTV reality show -- before he proposed in November. The mom-to-be says they want to wait until after she gives birth to say "I do."

"Being pregnant isn’t easy, but on top of that, I am planning my wedding, too! To say I have a lot on my plate is a complete understatement, which is why Corey and I have decided to go with our original plan and get married after the baby is born," she recently wrote on her blog.

"We are doing it backwards, I know! But, God’s timing is everything, and I am confident that this is the way things are supposed to be," she added. "Plus, I have a feeling our wedding photos will be extra adorable with our little baby in our arms instead of in my tummy!"

ET recently spoke with Patridge's former Hills co-star, Kristin Cavallari, who says they talk "all the time" -- even more so now that they will both be moms.

"I saw Audrina a few months ago, but we talk all the time," the mother of three said. "Audrina is reaching out about different mommy tricks and stuff and advice. She was just asking me what maternity jeans I loved and all of that fun stuff. It's really cool that she has been reaching out, and I was one of the first people that she told that she was pregnant."

Meanwhile, Cavallari exclusively opened up about how she makes her marriage to NFL star Jay Cutler work. Find out what she had to say in the video below.
