Perry 'doing good' after split

Katy Perry said to be "doing really good" following her split from John Mayer earlier this year.

The 'Dark Horse' hsinger was devastated when her two-year romance with the singer ended in February, amid claims he had cheated on her, but she is currently focusing on her upcoming 'Prismatic' world tour, which kicks off next month, in a bid to get over her recent heartache.
