Kate Beckinsale is often stunning her social media followers with her impeccably toned physique. She's built up a lot of muscle through her painstaking fitness regime. And not to mention, her flexibility is out of this world - as showcased by a video she recently posted on Instagram.

"Getting ready for the #criticschoiceawards with @robscheppy, @peter.savic, Clive, Myf and NO SCRUBS. Rob’s pretty thorough," Beckinsale captioned her video.

As explained in the caption, the British actress was getting ready for the Critics' Choice Awards while performing the impressive stunt.

Wearing a white top and underwear - with a cat conveniently placed on her lap - Beckinsale sat while her team applied makeup to her body and a hairstylist primped and curled her hair.

While a member of her makeup team applied makeup to her right leg, Beckinsale effortlessly raised her leg high up in the air while remaining seated.

When the above video went viral, people were in such disbelief as to the degree of flexibility shown by Beckinsale that conspiracy theorists began speculating that she had a rubber leg.

In an appearance with Jimmy Fallon, she talked about the rumors:

"My mum texted me and said that in England people think I've got a fake leg. I'm quite flexible, so now there's a thought that possibly I've got a rubber leg or a pretend leg. I've always been like that. I did a lot of ballet when I was a kid and now I can cause worry about a fake leg. That's really all I've got."

She then said that if the rumors were true, then she's "kept it awfully quiet for decades."
