'Workouts are paying off' – Lucy Watson wows fans with peachy behind in thong bikini on Instagram

She lives the high life of exotic holidays, private workouts and healthy vegan food, and the fruits of Lucy Watson's labour are visible in her latest Instagram shot,

The 26-year-old former Made in Chelsea star has just returned from a romantic break to Mexico with her long-term boyfriend James Dunmore, and showed off a cheeky snap from her holidays in a bikini.

Every inch of the reality star's gym-honed physique was put on display in the white skimpy two-piece, which features a high-rise thong, drawing attention to her peachy behind as she arched her back and leaned on the window, standing on her tiptoes.

The animal rights activist – who spends hours a week doing resistance training workouts with a personal trainer, well-documented on her Instagram stories – is seen peering out at some palm trees with her back to the camera, making her hard-earned figure the focal point.

Despite only sharing the picture a few hours ago, it has amassed nearly 30K likes so far, proving it's a hit with her fans.

One person told the fitness fanatic: "I aspire to have your derrière Miss."

Someone else put: "Gorgeous! The workouts are paying off girl"

A third added: "Wow! Look at that peach"

Just last week, Lucy announced on her Instagram that she had just bought a house with boyfriend James while in a romantic snap in a very similar white bikini. She captioned the shot: "adventures with this one are quite great @james_dunmore and today we bought our first house together".

Lucy made a name for herself on MIC for her sassy attitude and relationships with her male co-stars including Jamie Laing, Oliver Proudlock and Spencer Matthews, before finding true love with model James.

After leaving the show last year, she has gone on to become a vegan with a great passion for animal welfare, and has a cookery book available for pre-order called Feed Me Vegan.
