The reality star was pictured shopping in Los Angeles on Thursday (7 July) wearing a figure-hugging red halterneck jumpsuit and sky high wedges.
Courtney, who appeared on CBB in 2013, kept both hands on her blossoming baby bump as she walked along the street with a friend.
This is her first child with husband Doug Hutchison.
She announced the pregnancy at just four weeks back in May, saying she'd had to go public because others had been planning to reveal her baby news without her knowledge.
At the time she said she was "extremely overwhelmed" but happy.
Courtney, 21, and 56-year-old Doug's relationship has been in the headlines since they first got together. She was just 16 and he was 51. They met via an online acting workshop he was running, and he later said he thought she was much older, judging by her photos.
They married with her parents' blessing.
The couple briefly split following Courtney's appearance on Celebrity Big Brother, but reunited the following year and now plan to renew their wedding vows.
