Papers filed at a Los Angeles courthouse allege the 26-year-old TV presenter - daughter of rocker Ozzy Osbourne and his wife Sharon - owes $34,763.30 to the state of California dating back to 2009.
If found guilty Kelly - who recently moved into a new apartment in Los Angeles - could face fines or jail time and may have to forfeit assets if she can`t raise the money owed.
Although Kelly didn`t respond directly to the claims, she appeared to rubbish the allegations when she took to twitter yesterday (27.03.11), writing: "im getting less & less resilient to all the bulls**t stories i keep reading about myself i do enough stupid s**t no need to make things up! (sic)"
Kelly is reportedly worth $15 million thanks to her role on E!`s `Fashion Police` show, Closer magazine column deal, acting projects and her new job as the spokesperson for Madonna-s Material Girl clothing range.
Meanwhile, there was more bad news for the star on Saturday (26.03.11) when her credit card was stolen.
She revealed on twitter: "Someone stole my credit card and rented a car with it. What a dumb a*s you need to show I.d to rent a car!!! (sic)"
