Simpson's mum furious with her Parton performance
Jessica Simpson's mother reportedly lashed out at her daughter in front of Dolly Parton and US President George W Bush after the pop star forgot the words to the country star's 9 To 5 at Sunday's the recent Kennedy Center Honours.
Reports suggest Tina Simpson was furious with her daughter and told her she should quit the music business if she didn't want to put in the work.
