Classy: Kate Beckinsale managed to look effortlessly stylish as she headed out for a shopping trip in Los Angles on Monday

Rock Kate's cream of the crop

Oh to be 43 and look like THIS. Kate Backinsale proudly shared a selfie of her rock solid abs with her 570,000 Instagram followers earlier today. The British actress can be seen sporting a L*Space bikini top in the revealing snap, paired with some mismatched white bikini briefs.

Those readers lucky enough to be going away for some winter sun, do like Kate and try an athleisure style bikini - the extra coverage up top leaves much less room for potential wardrobe malfunctions. The matching bikini briefs are also available to buy online at Shopbop.

For anyone not jetting off to the Caribbean anytime soon (us neither, we feel your pain) opt for a crop like Kate's to wear by night. It will look fabulous with high-waisted, wide-leg trousers. Supermodel Kendall Jenner often wears her crop tops with distressed boyfriend jeans or even sporty tracksuit bottoms.

And it wasn't long since Kate showed off her figure in a candid selfie taken during a shoot for Shape magazine.

The 43-year-old Underworld star was seen posing in a black crop top and white pants as she captured the candid snapshot 'Laughing in bathrooms with friends. Ohhhhhh.'

Kate showcased her amazing, gym-honed body in the tiny top, with crossover straps emphasising her tiny waist. 

Never one to take herself too seriously, Kate also uploaded a close-up selfie of herself rocking a cosy knit.

Wow: Kate recently sent her followers wild with envy with a sexy mirror selfie taken on a break during her Shape magazine shoot last month

She joked: 'You can think you've had a reasonably good day until you get undressed at night and two small pieces of chicken fall out of your polo neck'. 

In another snap earlier this month, Kate was seen posing with her hands aloft her head while pouting into the distance, a stance she deemed as 'sniffing her armpit and twisting her head off'. 

Kate looked incredible in the image in which she wore just a white bandeau top with little else, to best show off her fantastic frame.

Her incredibly taut stomach was envy-inducing as she flaunted rippling abs and her tiny waist, honed by hours of hard work in the gym. 

Despite pouting into the distance in the perfect modelling pose, she was determined to poke fun at the pose. 

She added a caption on the image reading: 'It's Monday morning . Sniff your armpit and then try to twist your own head off who's with me'.  

Oops: Never one to take herself too seriously, Kate also uploaded a close-up selfie of herself rocking a cosy knit, joking she had secretly stashed some chicken inside 

As Kate sizzled in a bevy of snaps, she gave an accompanying interview to the health magazine about her lifestyle and her body. She said she steers clear of alcohol and has never had an entire glass of anything alcoholic.

'I don't drink alcohol,' she told the publication, 'I feel [its effects] very quickly, so I've never actually had an entire glass of anything alcoholic.'

The Love & Friendship star revealed the secrets of her enviable figure, which include five or six punishing works outs a week with a personal trainer ahead filming the fifth instalment of Underworld franchise, Blood Wars.

She explained she would rather exercise first thing: 'I basically wake up, eat breakfast, and then work out. I prefer to get it done in the morning.

'That said I don't naturally get up early. It would be much better for me if the entire world went to bed at 4 am and woke up at noon. But it doesn't, so I'm usually staggering around first thing.'

Taut and toned: Kate also poked fun at herself earlier this month as she shared another sizzling behind the scenes shot from her Shape magazine shoot
