The model and reality TV star, 32, is expecting her second child and pregnancy clearly suits her...
The former Miss Wales shared several bikini selfies this weekend (22 and 23 August) as she made the most of some sunny days in the UK.
Wearing a bright tangerine two-piece, Imogen wasn't afraid to show off her curves in a series of snaps posted on her official Instagram account to her 131,000 followers.
Alongside the sunny snaps taken in a Chelsea park, she said: "Last selfie in bikini before the rain hits us. I love the santorini bikini my fave from my business @chasingsummeruk give us a follow girlies...hot summer pieces www.chasingsummer.co.uk."
The bikini with gold hoop detail costs £39.99 on Imogen's website, which she set up this year to provide bikinis for curvy women.
She also told fans she's "loving her bump".
In May, Imogen and her long-term partner Adam Horsley announced they were expecting their second child.
To reveal the exciting news, she shared two pictures in a collage - one showing the scan of her unborn baby and another of herself showing her two-year-old daughter Ariana the pictures from her scan.
Alongside her photo, 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."
Since then, Imogen has kept fans updated with her growing bump. Earlier this week, she shared a post-workout snap from the gym. We're tired just thinking about it!
Earlier this month, Imogen revealed she is expecting another baby girl.
She told fans: "I'm soooooooooooooo happy to announce... I'm having another little princess. I can't wait to meet her in 3 months time.... a little sister for Ariana - can't wait to see them become best friends."
