TATU singer LENA KATINA has vowed to assassinate Charlotte Church, after the Welsh singer branded the pop duo "s**t".

Russian star Katina, who shoots a rapist in the head in the duo's latest video, and her bandmate Yulia Volkova were shocked by outspoken Church's scathing criticism - and they are determined to have their revenge.

Church originally said, "They just sound real s**t. And one of them's a minger (unattractive) as well. Their single's awful."

Katina counters, "I will murder her. She should come to Moscow and then I will shoot her in the head just like in our video.

"No one has heard of her in my country - yet where she lives, everyone knows who we are.

"She must be very careful with her big mouth because bad things can happen to people."
