Four-year-old Bella Devyatkina has risen to fame after appearing on a Russian TV talent show and speaking seven languages without a prominent accent.

Bella speaks languages belonging to three different groups: Indo-European (Russian, French, English, Spanish, German), Semitic (Arabic) and Sino-Tibetan (Chinese).

When the wunderkind appeared on the Russian talent show Amazing People, she shocked the judges. One of them, Evgeny, said, "When I saw what I've just seen, I understood how stupid I am."

She can think clearly in each language, and she correctly answered age-appropriate questions as well as questions related to the school curriculum, even though Bella is still three years away from starting school.

Some internet users suggested Bella's mother has stripped the girl of her childhood, but neuropsychologist Anna Semenovich said there was nothing to worry about.

"If the girl is learning languages through curiosity... it will only benefit her. She's not studying, she's playing!" Semenovich told the Russian newspaper KP Daily.

RT is a Russian multilingual television network.
