Ksenia Tsaritsina, 25, married Russian billionaire Aleksey Shapovalov last year after he presented her with a 70-carat ring.
The stunning brunette regularly shares pictures showing off her incredible figure with her 320,000 followers.
Recent images appearing to show her with fuller lips sparked speculation she has had some work done.

However, Ksenia insists she is entirely natural and has never gone under the surgeon’s knife.
She said: “Maybe I have such a bite that my lips look fuller on my face. Maybe I know how to pick the right angle for a photo, standing so that my body does not look natural.
“Bottom line is my relatives know the truth and one should not take it personally what others say.”

The mum-of-two admitted she has considered plastic surgery in the past but always decided against it.
She added: “The older I get, the less I would want to to change. I think this is wisdom.
“As for now, I do not plan to change anything about my looks.”

Last year, an Argentinian model was trolled online for having a “kilometre long hand”.
Belen Rodriguez, who lives and works in the Italian city of Milan, shared a snap with her 5.9 million social media followers this week only to be plagued with abuse.
The 32-year-old found herself in the centre of the drama with hordes of her supposed fans taking aim at her.
