To tell you a little secret, she'll perform two songs in the show! One of them is Shady Lady, with which she represented Ukraine at the Eurovision Song Contest back in 2008 and finished second.
Later she also had a chance to try out the stage as the Host, together with Timur Miroshnichenko and Dmytro Borodin. You can actually see her rehearsing that one in our video below!
Also check out a gallery of her rehearsal below!
The Final of the Junior Eurovision Song Contest will be held this Saturday at 20:15 CET, live from Kyiv, Ukraine.
