Masha told the cameras, "Sasha and I dated for a year. Then we were married for a year and got divorced because he met his second wife. She got pregnant, and he came to me and said, 'I want a divorce.'"
However, Emily, a 29-year-old originally from Portland, OR, took to her Instagram Stories recently and denied the allegations, according to screenshots captured by 90 Day Fiance Instagrammer John Yates.
Emily posted alleged photos of Sasha and Masha's Russian divorce certificate as well as what appeared to be the Russian birth certificate of Sasha's second child.
"Sasha and Masha's divorce certificate from 2012," Emily wrote on one document, which appeared to be written in Russian.
And on another document, Emily claimed, "Sasha's second son wasn't born until 2014."
Considering there was allegedly a two-year gap from when Sasha and Masha divorced and when his second wife welcomed her baby, the documents -- if valid -- appear to demonstrate Sasha was no longer married to Masha when he got his second wife pregnant.
According to Emily, Sasha married Masha when he was 22 years old and they welcomed his first child together.
90 Day Fiance's broadcastshave shown Emily claiming Sasha's relationship with Masha was "doomed to fail," and Sasha saying it was because Masha was "a difficult" and "crazy" person.
Meanwhile, Sasha has been showing he divorced his second wife because he said she didn't like it when his body got very muscular due to his sudden interest in fitness and personal training.
The latest90 Day Fiance episode showed Sasha and Emily, who was nine months pregnant at the time with Sasha's third child, meeting up with Masha at a restaurant to discuss the near future.
Emily and Sasha planned to move from Russia to the United States after their baby's arrival, so Emily asked Masha if her son Daniel would be able to visit them in America down the road.
Emily was hoping she and Masha could maintain a healthy relationship for Daniel's sake.
Masha wasn't happy about the idea of Sasha leaving the country when he had two other children to worry about and take care of. She called him a selfish man.
"Where the wind blows... a man flies," Masha vented to 90 Day Fiance's producers during the latest episode. "His family will not keep him. His children will not keep him.. Men only think about themselves."
After a long and apparently exhausting conversation, Masha gave her blessing for Daniel to visit America, as long as that's what Daniel would like to do.
