Leonna Mayor's job is to race horses, but with these pictures the young jockey will have hearts racing across the country.
The stunning 22-year-old is an apprentice at Alastair Lidderdale's stable - and already has 31 wins to her name.
And while her fledgling racing career remains in its infancy, these pictures will send her shooting to the forefront of all race-goers minds.
Weighing in: Mayor takes to the scales at Kempton Park in Surrey
Mayor first appeared in MailOnline 18 months ago during a photoshoot alongside a number of other young female jockeys.
She revealed her desire at the time was to become a top jockey in racing circles. And there was also a revelation about her slightly embarrassing modelling past.
She said: 'My main ambition is to be known as a good female jockey and to get to a situation where trainers want to use me rather than my agent having to ask them.'
'Winning my fourth and most important race of the year (in 2011) on Thunderball at Pontefract when the owners could have used a more experienced jockey was a highlight.
Fitness regime: Mayor has revealed how much dedication is needed to remain trim for racing
She added: 'I did modelling as a youngster and was pictured wearing a hideous pink tracksuit in the Argos catalogue.'
Staying in shape is a key element of her day-to-day life as a jockey, but has admitted staying trim is a constant battle.
Leonna, 22, told the Daily Star: 'It is weird having to adjust your weight for different races but it becomes second nature.
Lacy racer: Mayor certainly sets the pulses racing on and off the track
'It makes dinners out difficult and, after a long day, the last thing I feel like doing is cooking a complicated meal. I eat a lot of soup and treat myself to a takeaway if I get a win!
'If I need to lose a pound or so, I
sweat in a hot bath. One of the lads suggested a couple of glasses of
wine the night before a race to dehydrate.'
Judging by these pictures, her fitness regime is working just fine.
