Kate Upton flaunts her curves in thong leotard during steamy tennis shoot

Kate Upton is one of the most sought-after models in the fashion industry.

And we’ve all gawped at her as she has shown off her bikini body on the cover of Sports Illustrated.

So in the spirit of Christmas, the 25-year-old has shown just how much effort it takes to keep her enviable figure in check.

The model stripped down to a tight-black leotard for LOVE Advent Calendar’s iconic festive countdown.

Every day in the lead up to Christmas, the brand has been releasing videos of the hottest names in fashion in a series of raunchy scenes.

Today, the blonde bombshell took centre stage with a saucy tennis routine.

In the short clip, which was shot by Phil Poynter, Kate showed off her sports skills.

Not only did she manage to whack numerous balls that were pelted at her, she managed to do so in towering heels.

In keeping with this year’s “stay strong” theme, she worked up a sweat by swinging her racket back and forth.

At the end of the clip, Kate dives onto the floor as she attempts to make a tricky shot.

In the closing frame, she flaunts her toned body and flexes her muscles.

Speaking about the quirky video, the model revealed: “It’s silly and fun, and I love shoots where I don’t have to take myself too seriously.”

Kate's scene follows a raunchy sledgehammer routine carried out by Victoira's Secrets' Bella Hadid. 

Many have commented that this year’s LOVE advent calendars have been the best yet.

In the first week, Rita Ora carried out a sexy dance in a skimpy cut-out leotard. And supermodel Barbara Palvin got eyes-popping with a sensual pole dance.
