Kylie credits self-help book for inspiring comeback

Kylie Minogue credits a self-help book with her recent career resurgence.

The 'I Should Be So Lucky' singer has gone through some big changes in her life both personally and professionally - including her split from Andres Velencoso to her upcoming album 'Kiss Me Once' - and she says it was an "epiphany" when she signed with Jay Z's record label Roc Nation.
