"Ukraine’s entry this year is the rapper and singer duo Alyona Alyona and Jerry Heil."

Jerry 'Heil'

“There are many wars now in the world and, of course, it is not easy to constantly keep attention on yourself so that people do not get tired of our war."

EDIT: upon further research of Jerry Heil:

'Heil began using her alias at the age of 15. After registering for the Russian social media service VKontakte, she used the name Jerry Mouse, referencing the cartoon character of the same name. She then changed Mouse to Heil, citing her desire to use whatever American surname she saw on the Internet first.

She has expressed her embarrassment for the backstory behind her stage name, calling it "moronic".'
