Rosie Huntington-Whiteley displays her abs in a brown sports bra as she showcases her impressive strength during gruelling workout

Rosie Huntington-Whiteley displayed her abs in a brown sports bra as she posed for a sizzling Instagram selfie on Friday.

The supermodel, 39, showcased her impressive strength while giving fans a glimpse into her gruelling workout.

Rosie modelled lycra gym leggings from ALO and matching socks while showing off her muscular frame.

The mother-of-two shares son Jack, eight, and daughter Isabella, three, with her fiancé Jason Statham, 59.

The low-key British couple, who live in Los Angeles, first began dating in 2010 after meeting at a party in London and experiencing what Rosie called 'instant chemistry'. 

Jason and Rosie got engaged in 2016, with the model revealing they had taken their relationship to the next level when she flashed her impressive diamond ring at the Golden Globes, and they're now parents to two children.

Speaking about their plans to marry after Jack was born, Rosie said: 'I think the time will come. It's also not a huge priority for us.'

She has also addressed the couple's 20-year age gap, saying: 'His knowledge and strength are really inspiring and attractive, and that can come with a man who's had a bit of time.'

While Rosie is one of the world's top supermodels, she has previously spoken about facing rejection in the industry. 

Speaking on the Reign with Josh Smith podcast, Rosie revealed how now she doesn't see rejection as failure and instead views it as something that wasn't meant to be. 

She told the host: 'There is a lot of rejection in this industry and there have been some really tough lessons with that… even now there's rejection.

'I don't always get the jobs that I want and some things don't work out the way that I want them to.

'I remember being sent home from a job once and that was very painful and that really hurt my soul.'

She reflected: 'But you know, I was very, very young. But if a job doesn't work out, I kind of think it wasn't meant to be or I'm knocking on the wrong door and I go find opportunities elsewhere where I'm embraced.

'I can never really consider something that didn't work out or rejection as a kind of failure. I see it as an opportunity for deep growth and actually, when I think of the successes that I've had over the years, which I feel very privileged for having they're so fun.' 

The star also opened up about the lessons she has learnt from her husband as she revealed he encouraged her to be her own advocate and not be controlled by the industry.

She explained: 'When I started, you kind of join an agency and they take control of your kind of diary and your schedule and you're sort of told what you're going to do and when you're going to do it.

'I think around my sort of early mid twenties, there was definitely a point, and I remember it was actually Jason who is a great advocate for himself, but also really been such a backbone of strength and support for me as well, because he's taught me so much.

'It was a reminder for me of, "no, no, no, I'm In control and I'm in control of some of this".… I also live with someone [Jason] who uses manifestation and self belief as a real tool and I know it's really infectious.'

Rosie also discussed how periods of struggle in her life have helped shape her as a person.

She added: 'I feel for me, those dark sort of times or those struggle times, they're kind of what make me interesting. It's like they've roughed me up a little bit.

'That's what makes you kind of layered and multifaceted as an individual and as a woman. So I just try and turn things around and make it a positive.

'It doesn't happen overnight, sometimes things really sting and they really hurt and it takes a while to see why it didn't happen, but I always try and see things that feel like they are happening at you that they're happening for me.'
