The former Big Brother star was pictured alongside her sis today (27 June) as they enjoyed a hack through the countryside together.
Both girls appeared to be having great time and Imogen was quick to share this photograph of them with her Twitter followers.
Alongside the picture, Imogen commented: "Riding this morning...me and my sis ❤"
Before heading out, Imogen had uploaded another gorgeous photograph of little Ariana, who she gave birth to in February, dressed all in white.
She tweeted: "Little miss poser ❤" So cute!
