American Singer Kelly Clarkson Claims Her Estranged Husband Defrauded Her Of A Fortune 

American singer, Kelly Clarkson has claimed her estranged husband, Brandon Blackstock defrauded her out of a fortune.

Clarkson just filed legal documents with the California Labor Commission, claiming her ex, Brandon Blackstock, who also served as her personal manager, defrauded her by charging exorbitant fees, and she wants all of the "loot" back.

Among other things, Kelly says Brandon wasn't legally allowed to operate as a talent agent, because he never obtained a license.

Kelly has been one of the high earners in the music industry for a long time now, so the commissions she's paid are huge. She was with Brandon's company, Starstruck Management, for 13 years and if the commission accrued over the years is calculated, it means it's a fortune.

Bryan Freedman, lawyer for Starstruck, tells TMZ: "The labor petition conveniently ignores the fact that Kelly had her own licensed talent agency CAA at all times. While Starstruck Management Group provided talent management services on her behalf, it did so at all times that CAA was her agency of record."

He continues, "It is unfortunate that Kelly is again attempting to avoid paying commissions that are due and owing to Starstruck to try and achieve some perceived advantage in her ongoing custody and divorce proceedings."

Kelly was sued by Brandon's company in September, Starstruck Management, claiming she owed the company $1.4 mil in commissions.

This is the latest in what has become a nasty divorce.

Besides money, Kelly and Brandon initially fought over custody of their kids. Brandon wanted their 2 kids to stay with him at the family's Montana ranch. Kelly said she did not want the kids shuttling back and forth between states, and L.A. has been home base for the children. The judge agreed, and now Brandon can only see the kids every other weekend.
