Alicia Keys feuding with Lupe Fiasco?

Alicia Keys is reportedly upset that Lupe Fiasco used one of her unreleased songs without her consent.
The R&B superstar, who collaborated with the rapper on a song, entitled 'Letter To The Beat', previously recorded a song with Chad from the Neptunes for her 2007 album As I Am.
According to All Hip Hop, the track was never finished and was meant to be used at a later time but Chad gave the vocals and the beat to Fiasco without Alicia Keys's consent.
Reports claim that Fiasco's use of the original Keys song has infuriated the singer.
Keys's longtime music engineer Ann Mincieli revealed her disappointment with Fiasco's decision to use the song, on Twitter.You can buy Alicia Keys Tickets and sell Alicia Keys Tickets through YourTicketMarket.com.
