he's not actually 53m in debt
he spent 53mil on whatever he's been doing
he does have debt though, just not that much
he has assets worth a stuff load. an absolute stuffload. think of all the songs he has made that were huge hits. he can sell the rights to those songs, or sell his homes, or his other expensive stuff im sure he has, and bam hes out of debt. but he would rather just earn the money/get money from deals/sponsors etc to pay off the debt so he doesnt have to lose his homes or sell off the rights to his music or other such assets.
