Four year-old Bella Devyatkina speaks seven languages.
The polyglot, from Moscow, showed off her linguistic abilities on Russian talent showAmazing People, speaking English, German, Spanish, French, Chinese, Arabic and Russian.
The show lined up adults who speak each language, and Bella skipped between them, switching languages effortlessly and even singing a song.
She has strong literacy skills too. In English, she's asked to read a question that asks: "Which dinosaur has two rows of bony plates that run along its back and tail?"
"Stegosaurus," she answers, without missing a beat.
Apparently her mother hired multiple nannies, who teach her different languages.
If she wins the competition, she could take home more than $20,000 in prize money.
The rock star performance has hit 45,000 views on YouTube.
Although hard to understand, it's a mesmerising performance.
Psychologist Nesha O'Neil told news.com.au in 2014 that children are highly susceptible to picking up languages, during the trial of a government preschool language program.
"The idea of a play-based app with a program of immersing them in a second language is brilliant," Ms O'Neil said. "The age of three and four is when there is the most amount of brain development, and it is absolutely appropriate to learn a language."
Typically, children whose parents speak more than one language also perform better on IQ tests.
