"Staff at his shuttered carrier Kingfisher Airlines, which owes banks over $1 billion, have not been paid in 15 months. But he has not given up efforts to sell the airline. This summer he hosted a house-warming party at his new digs in London," the magazine added.
Forbes India had said in October 2012 about Mr Mallya that the 'King of good times' is having nothing but bad times lately.
A day after Forbes India Rich List of 2012 had put his net worth at below $1 billion, Mr Mallya had tweeted that he was thankful to the "Almighty" for being out of the billionaires' club.
"Thanks to the Almighty that Forbes has removed me from the so-called Billionaires list. Less jealousy, less frenzy and wrongful attacks," he had posted on the micro-blogging site.
