Since her arrival back in November, Imogen has been completely smitten with her baby girl and has been keeping fans updated with the tot's progress on the photo-sharing app.
Sharing another gorgeous photo of her daughter earlier today, Imogen couldn't resist getting all sentimental over Siera, telling her followers she is "perfect".
Imogen said: "I've got a little poser on my hands.. My gorgeous girl....she's perfect."
In her photo, Siera is pictured lying down while wearing a sweet, pale pink all-in-one. Just look at those cheeks!
Not surprisingly, Imogen was inundated with compliments on her youngest child, with many telling the former Big Brother star just how cute her bubba is.
One user wrote: "Aw so precious Wee cutie pie xx." While another commented: "What a beauty!"
Imogen first welcomed Siera on 20 November, later revealing she had been born at 11.13am and weighed just over 7lbs. She shared a precious snap of Siera's teeny tiny fingers on Instagram to announce her arrival.
Siera is Imogen's second child with her long-term beau Adam Horsley. They are already parents to their two-year-old daughter Ariana Siena.
