Tamara Ecclestone showcases her incredible figure in a series of plunging swimsuits in sexy new shoot

She regularly hits the gym to maintain her lithe physique, so it's no wonder that Tamara Ecclestone isn't shy about showing off the fruits of her labour.

The Formula One heiress, 31, flaunted her stunning figure as she posed for a sexy swimwear shoot in Los Angeles.

The mother-of-one looked flawless as she modelled an array of beautiful swimwear, including plunging one-pieces and skimpy bikinis.

Despite being a busy working mother to daughter Sophia, 18 months, with husband Jay Rutland, Tamara told MailOnline running around after her little one helps her to stay in shape.

She said: 'It's a case of never sitting down running after a toddler. I just don't have time to work out, but we have fun walking in the park with the buggy and the dogs'

'I'm constantly on the go. Balancing work and motherhood can be tough, but Sophia is great and so it makes things easier being able to take her wherever I go.'

In one racy snap, Milan-born Tamara displayed her ample cleavage in a leopard-print swimsuit boasting a sultry, lace-up design.

Her dip-dyed brunette tresses were styled into glamorous waves as she sported a full-face of perfectly-applied make-up.

Tamara looked toned and tanned to perfection as she modelled the white Sports Luxe Honolua swimsuit in another snap.

The bright one-piece, which featured netted shoulder detail, boasted a risqué zip-up neckline which was undone to her waist to accentuate her cleavage.

Her bronzed pins were on full display in the athletic number, while her ankle tattoo was also visible on her right foot, featuring a lock and key along with the quote 'the best is yet to come.'

The Show Beauty founder also modelled a classic black bikini, consisting of a simple black top and skimpy bottoms, her wedding band from Jay on full display.

Snapped by photographer Karis Kennedy and made up by Sarah Maxwell, a classic pinky-nude manicure and pedicure completed her flawless appearance.

The Ecclestone family returned to London two weeks ago after jetting out to California for an extended summer holiday at the end of July.

There, they were joined by the socialite's older sister Petra Stunt and her family as well as the siblings' mother Slavica, 59.

Their trip was their twelfth jaunt abroad in not as many months after holidaying in the Bahamas, Milan, Lake Como, Dubai and New York so far this year.
