Britney Spears will not take her sons on her tour to Russia after receiving death threats.

The pop star will reportedly stay in Finland and fly in just for the two concerts in St Petersburg and Moscow next week.

Straight after the Moscow gig, she will fly to London to be reunited with sons Sean Preston, three, and Jayden James, two.

A tour spokesman said: "Originally, both boys were to accompany Britney but she was against taking them because of these constant threats."

The blackmailer's identity is currently unknown.
