Beyonce Knowles’ father, Matthew Knowles has helped build his R & B singer daughter into a multi-millionaire – but has he fallen onto hard times himself while doing it?

According to the state of California it seems so – by their records the music executive owes more than $12,000 in delinquent taxes.

And with the finances of the Golden state not looking so golden these days, they are going hell for leather to recoup the debt - filing a $12,115 tax lien against Knowles on March 9.
