A Kate Upton look-alike named Ania has even the Sports Illustrated cover model herself admitting a remarkable resemblance.

"Me as Kate Upton," Ania tweeted on Sunday along with a photo of the Russian posing in a fur-rimmed jacket like the one Upton wears in the 2013 Sports Illustrated Swimsuit Issue cover photo.

Ania's tweet included the hashtag #doppleganger.

"Amazing," Upton replied to her look-alike's Twitter post .

Upton retweeted the photo of her doppleganger and set the Twittesphere on fire.

"Kate Upton, imitation is the best form of flattery, well done," tweeted Ivan Bart.

"Wowzers Batman," wrote Twitter user Kev.

"Have you seen @KateUpton's doppleganger the beautiful @Huliganjettaa?" Ariana tweeted, referring to Kate Upton's look-alike by her Twitter handle.

In an interview released Friday for The Thread, Kate Upton explained why she prefers to the beach in a bikini.

"I think finding clothes is a challenge because of my body," Upton said, adding, "you just need to aware of that and find something that works on curvy women. I prefer string bikinis, just seems like it fits better. I think going a little bit smaller is better because it offers you more support."

We're guessing most male beach-goers are not upset about Kate Upton opting for a smaller bikini.

Upton also discussed the infamous Sports Illustrated cover shot, her second for the magazine.

Instead of the typical tropical settings, Kate's cover shot for the 2013 Sports Illustrated swimsuit issue was shot in the bitter cold of Antarctica.

"When I went to Antarctica, it was a pretty crazy shoot because usually it's like bikini, warm weather," Upton said. "It was about fifteen to twenty degrees, and with the wind chill it made it feel like 1 degree. No other fashion magazine has ever been there or shot there so no one knew what to expect."
