R&B BEEF!! ESTELLE CLAIMS THAT RIHANNA SWAGGA JACKED HER STYLE!!!

London-bred singer Estelle has enjoyed a reasonable amount of success by any standards. Her 2008 album 'Shine,' featured collaborations with Kanye West, Will.i.am, Cee-lo and John Legend, and her lead single 'American Boy' was nominated for three Grammys, an MTV award and was certified platinum in the U.S..

Despite her various successes and reports that her upcoming album will feature cameos by heavy-hitters like Mary J. Blige, Jay-Z and Lil Wayne, we keep hearing rumors about Estelle throwing shots at fellow singer Rihanna.
