Cara, who found fame in The Only Way Is Essex, is set to give birth in the next five weeks and posed for a new picture while standing in the mirror at home.
With her long brunette hair pulled back into a high ponytail, Cara gently cradled her blooming tummy while snapping the selfie.
Sharing it on Instagram, she told her followers: "Baby Bump #35weeks #5weekstogo 21lbs up!!! #BabyHarris."
She also posted both a pink and blue heart emoji. Oooh, which one will it be?!
In September, Cara revealed she was expecting a baby with long-term boyfriend Daniel Harris.
The news came six months after Cara suffered the heartbreak of a miscarriage, which tragically happened five months into a previous pregnancy.
Since announcing their baby joy, Cara has kept fans updated by sharing lots of bump pictures and, earlier this month, she even Instagrammed an image from a recent scan.
Cara will be in good company when baby Harris comes along, as best friend and former TOWIE co-star Billi Mucklow gave birth to son Arlo earlier this year.
And more recently, former TOWIE star Sam Faiers became a mum to a baby boy - on Tuesday in fact!
Not long to go now, Cara!
