Larisa Sinelshchikova was born on February 10, 1963, in the village of Psebay in Mostovsky District in Krasnodar Krai.

After finishing secondary school #4 in 1979, she left for Moscow and entered the Russian Academy of Theatre Arts (GITIS).

In April 2014 it became known that Sinelshchikova agreed to sell 51% of registered capital of the Red Square companies to Arkady Rotenberg.

Andrei Baturin, the official representative of the businessman, explained that Rotenberg’s interest in the company is connected to the growing importance of content for modern media and the need to rely on ‘the first and the best’.

Sinelshchikova’s share was distributed among producers Viktor Drobysh, Vladimir Dubovitsky, Igor Matvienko, Konstantin Meladze and Maxim Fadeyev, with whom she had worked for many years.

The gossip journalists noted Sinelschikova's great contribution to Ernst’s achievements as head of ORT and Channel One.
