It comes as she launches her third album in the UK.
Keys’ publicity team at Sony BMG commissioned Silence to design and promote a Facebook application to coincide with the album’s release.
The ‘As I Am’ application, named after Keys’ album, is the billed as ‘the internet's first socially-powered self-help tool’.
It will act as a Facebook forum for Keys’ fans to discuss how they’ve overcome problems in their lives.
Silence’s Lee Henshaw, who conceived the application, said: ‘This is a challenge for publicists.
There are no editors to talk to, so to reach this community you have to act like a friend, rather than an advertiser.’
