The model and former Big Brother star turned heads as she arrived for the Ego Professional x Macmillan Cancer event on Tuesday evening (28 July).
Imogen looked senstational in a figure-hugging black dress and heels. When we saw these pictures we were thinking there was something very Kim Kardashian about the whole look... and we were right!
This particular dress was recently pictured on Kim, who is also pregnant. If you fancy getting your hands on it as well, head over to Spotted On Celeb, although it will set you back a pricey £240.
The star announced in May that she's expecting her second child, a little brother or sister for adorable daughter Ariana, two.
At the time, she said: "Guess what?! I'm going to pop! This little Madam can't wait to be a big sister in November! She's going to be the best #novemberbaby."
