Well looks like Rihanna learned this lesson the hard way. By acting irresponsible you can lose a LOT of money and in this case $47,050.
TMZ reports that Rihanna's ex-accountants have been trying to get the singer to sit for a deposition in a lawsuit RiRi filed against them.
Rihanna claimed that they mismanaged her money and owe her millions yet the accountants claim Rihanna's the one who's at fault.
Well she's been blowing of these depositions like it's her job costing them ALOT of money in attorneys' fees so the judge is now fining Rihanna $47,050 dollars for the ex-accountants legal bills.
