The pregnant Celebrity Big Brother star uploaded an image to Instagram on Sunday (19 June) showing husband Doug Hutchison kneeling in front of her bare bump.
Her caption read: "Happy first Fathers Day to my amazing hubby! #fathersday#babyontheway."
Courtney and Doug celebrated their fifth wedding anniversary last month, with a loved up Courtney gushing: "5 years ago I married an incredible man & we are celebrating by renewing our vows in a very special place! Stay tuned."
Their marriage made headlines because Courtney was just 16 at the time and Doug was 51. Their relationship started after they met via an online acting workshop he'd been running.
They exchanged emails and Doug later said he thought she'd been at least 21 judging by her pictures.
They married with her parents' consent.
Following Courtney's appearance on Celebrity Big Brother in 2013, the couple went through a rocky patch, separating but remaining close friends. Doug even remained as Courtney's co-manager.
But a year later the romance was back on, followed by a re-engagement and plans to renew their wedding vows.
Last week, the reality star lashed out at critics who had bodyshamed her, saying: "Stop fat shaming pregnant women. Honestly, if our society thinks that it's actually ok to say a pregnant woman is 'fat' there's something seriously wrong with it."
