Alicia Keys' son is her ''biggest fan''.

The 34-year-old singer has two boys, four-year-old Egypt and six-month-old Genesis, with her husband Swizz Beatz and her oldest child loves his mother's music.

She revealed: ''The younger one is too young (to listen to my music), but the older one is four and he's my biggest fan.''

Alicia believes her kids have inspired her to become an even better songwriter.

The 'We Are Here' hitmaker has gained a greater appreciation of life from her family and that new-found understanding has filtered into her music.

In an interview with the new issue of Germany's Glamour magazine, she said: ''Since I have had children I write better songs. They made sure that I understand life and love on a whole other level now. Through them I have discovered sides of my personality which I previously didn't realise existed.''

Alicia - who married Swizz in July 2010 - doesn't think there's any difference between who she is at home with her family and who she is on stage performing for her thousands of fans.

She explained: ''For me there's no difference ... I make music about who I am and how I live.''
