The mum-of-one admitted she is desperate to expand her brood and would love to fall pregnant again in 2015.
Feeling left out after many of her friends are expecting, Imogen said: "I'm really broody right now."
Speaking to the Mail Online, Imogen confessed she would love to start trying for another baby with her long term partner Adam Horsley.
"I don't want to scare Adam away... but, I want to start trying in January for the New Year," she explained.
The couple are already parents to their one-year-old daughter, Ariana Siena, and since her little girl's birth last year Imogen has been loving every minute of being a mum.
She added: "My life has changed for the better, I wouldn't swap it for the world, Ariana is everything to me."
So much so, that Ariana has even inspired a career change for the Welsh model!
Loving being able to pick and choose her daughter's very cute wardrobe, Imogen has launched her own online children's clothing boutique, Aribella Boutique.
The website specialises in hand-made traditional baby clothes and little Ariana has landed her first modelling job as she is the face of her mum's new venture.
Although the website only caters for girls' clothes at the moment, Imogen revealed she is planning to design a collection for boys too.
So, if another baby were to pop up... sounds like she'll be fully prepared!
