It might be her first time appearing in The Only Way Is Essex, but the Southend-On-Sea stunner has already starred on another reality show where she was very much in the spotlight.
For those of you who can't quite place her, Imogen was one of 13 finalists on the 7th cycle of Britain And Ireland's Next Top Model in 2011.
In fact, she even made it to the final five of the modelling show, which was eventually won by Jade Thompson.
Imogen was sent home in a double elimination at the end of the penultimate episode after host Elle Macpherson called her pictures "cheesy". But she did get to enjoy a working trip to Miami at the show's expense first.
Fortunately for Imogen, though, this wasn't the end of her modelling career, as she was soon snapped up by Nevs Model Agency and is still on their books.
Although Imogen is yet to star in an episode of TOWIE, she is currently with the cast in Marbella.
She joins the show with best friend and fellow newbie Robyn Althasen.
They will appear in the ITV2's show's summer spin-off which airs on June 22.
Before flying to Marbella in relatively secrecy to join the cast, Imogen took to Twitter to post the message: "Sometimes in life you do the things you never thought you were going to do......"
Earlier this week, we told you that Imogen and Robyn had arrived in Marbs and were already causing a stir with the boys.
Fresh blood - we love it!
