Rachel, who calls herself the “No1 tennis influencer”, left her 306,000 followers in awe with her latest raunchy pic.
The 26-year-old, who has previously been hailed as the “Queen of the court” by fans, left little to the imagination as she posed in front of a net.
But it was her low-cut top that flaunted almost every inch of her curves that sent fans into meltdown.
It was described as “gorgeous” by one admirer, while another commented simply with “beautiful”.
Another said they were “speechless” after viewing the image.
And a fellow fan said that they were “in love”.
This comes after Rachel caught the eye as she starred in a new energy drink advert.
Rachel, who reckons she was good enough to become a pro tennis player, now has more than 300,000 Instagram followers.
One reason might be her colourful array of minimal outfits, including pink training gear.
But she also posts playing tips for her army of admirers.
The social media celebrity from St Louis is also a writer with a major in nutrition and fitness from the University of Missouri.
