Kelly Brook stripped down to a swimwear as she shared behind-the-scene snaps from Celebrity Race Across the World.

The former glamour model, 44, and her husband, Jeremy Parisi, are currently competing in the second series of the BBC show.

Taking to Instagram on Thursday, the actress shared a carousel of snaps from their travels. 

In one snap, the star looked incredible as she leaned on a window sill and posed in a colourful swimsuit, flaunting her stunning curves, while in another she beamed at the camera in the one-piece as she put her towels up to dry.

Kelly captioned the post: 'Living our Best Backpackers Life in this Jungle Paradise.'

Her fans flooded the comments as they gushed over the star, with one person writing: 'Love it! You made me laugh, like you were on holiday rather than in a race.'

A second added: 'Loving the show so far, can't wait for next week.'

'Really enjoyed watching the show, You two are the best xx,' another wrote. 

It comes after Kelly stunned viewers as she revealed her real name during the opening episode of the BBC show on Wednesday. 

The presenter was born as Kelly Anne Parsons, but adopted the surname Brook when she kicked off her modelling career.

Despite that being the name she's known by, it's never been added to her passport.

She said: 'My happy place is in my garden in my wellies, no makeup, hair up. To think that I was like a pin-up and I do calendars, it's just all an illusion - like it's not who I am at all.'

'Kelly Brook doesn't actually exist, it's not even a real name, it's never even been on my passport or anything. In my mind I'm Mrs Parisi, Jeremy's wife.'

The star recently recalled how the trip was the 'honeymoon from hell' as she reflected on the challenge in an interview.

After mistakenly believing the arduous 12,500km trek across South America would be an alternative honeymoon, Kelly told Closer magazine: 'We hadn’t had a honeymoon and I said to Jeremy we should consider this as a fun alternative, a once-in-a-lifetime experience. 

'At times it was the honeymoon from hell – at other times it was absolutely glorious. It’s got to be the most memorable honeymoon ever!'

Detailing how the journey allowed them to open their eyes to their relationship dynamic, she continued: 'I didn’t realise how competitive he was, like, crazy competitive. I’m much more about the experience.

'I think I got on his nerves because he was full steam ahead. If Jeremy was doing the race alone, he’d have finished it in a week. I was kind of slowing him down a little bit and I was like, let’s have a Brazilian barbecue one day or let’s go to the beach.
