Rocker Ozzy Osbourne's eldest son Louis has been declared bankrupt.

The 38 year old, from the Black Sabbath frontman's first marriage to Thelma Riley, was recently named in bankruptcy papers filed at a court in Birmingham, England, according to Britain's Sunday Mirror newspaper.

Louis Osbourne worked as a Dj and a music shop assistant before setting up his own record label. It is not known what has caused his financial crisis.
