Jeremiah 'Jeremy' Davis, 31, has filed a federal lawsuit against former band mates Hayley Williams and Taylor York for breach of contract and fraud

Living in the real world can be a harsh reality - as Hayley Williams of the band Paramore is now finding out.

The lead singer is being slapped with a federal lawsuit by former bandmate and bass guitarist Jeremiah 'Jeremy' Davis, 31, over claims she refuses to pay him his cut of royalties and is also lying about who actually wrote their music.

Also named in the lawsuit is band member Taylor York, Mark Mercado and Fly South Music Group who provided personal artist management services for the band, as well as Jason B. Childress and Curo Financial Management, LLC who provided business management services for the band.

Davis is suing for breach of contract and fraud.

In court documents obtained exclusively by Daily Mail Online, Davis claims Williams, 27, and York, 26, agreed to share authorship of songs written for the 2013 self-titled album Paramore.

He says he contributed to all 17 songs on the album and takes credit for the overall 'funk style' of the tracks - especially their biggest hit song Ain't It Fun that reached number one on Billboard charts, sold more than 2 million copies and won a Grammy for Best Rock Song in 2015.

The band's other hit singles include Still Into You, The Only Exception and Misery Business.

However, court papers state Davis was not credited for any of the work he did on the album besides one 'throw away' song.

The lawsuit claims: 'Plaintiff is not listed as a co-author of any musical compositions embodied on the album Paramore, with the exception of a partial, one-minute-ninety-second interlude entitled 'Interlude: Holiday,' which is only available as part of the liner notes included with a purchase of the entire Paramore album, but not individually purchased singles.'

Davis then goes on to blast Hayley in the court documents for publicly crediting him in interviews for his role on Ain't It Fun but behind the scenes not giving credit to where credit is due.

The suit also says Davis has never been properly compensated for his co-authorship of the music and as a result he 'suffered substantial monetary damages as a result of Defendants' unlawful conduct, including, but not limited to, being excluded from participating in income arising from royalties, licensing, and other monies generated from the musical compositions and sound recordings embodied on the album Paramore.'

Courtroom fight: Davis, who was a founding member of the group Paramore but left in December 2015, wants to be compensated and have copyrights edited to add his name

Davis then goes after Mercado, Fly South Music Group, Childress and Curo Financial Management in the lawsuit claiming they all failed to appropriately advise him, which they were hired to do.

Paramore was formed back in the summer of 2004 with Davis as one of the original members. He left the band this past December.

The band posted a message on Facebook to fans that reads in part: 'We've written and re-written this countless times and there's just not a good way to put it... Jeremy is no longer going to be in the band with us.

'To be honest, this has been really painful. After taking time to consider how to move forward, we ultimately found that we really do believe Paramore can and should continue on. And so we will.'

Davis is now asking a judge to rule the copyrights be edited by Williams and York to add his name as well as be awarded direct damages and foreseeable consequential damages to be determined and attorney fees.
