Katherine Jackson is furious that AEG Live wants her to pay its $1.2 million legal costs.

A jury ruled on October 2 that the concert promoters were not to blame for her son Michael Jackson's death in 2009 and not wrong for hiring disgraced physician, Conrad Murray, to care for the 'Thriller' hitmaker before his This Is It comeback concert series in London, as he was neither ''unfit'' nor ''incompetent'' at the time, and the company is now asking a judge to make the Jackson family matriarch cover all of its court fees.

A source told gossip website TMZ.com that Katherine is irate and thinks many of AEG's so-called ''expenses'' are bogus.

The company has included an itemised list of its costs from the five-month trial in new court documents, including $540,000 for models and blow-up court exhibits, $118,000 for unnecessary depositions, $53,000 for process servers and $20,000 for 1,000 pages of jury instructions and other documents.

AEG also wants Katherine to pay its $9 parking fees.

The judge overseeing the case has yet to decided if she will be held responsible for the legal fees.

The 83 year old filed court documents seeking a new trial in her wrongful death lawsuit against the concert promoters earlier this month.

It was previously revealed that she was still hopeful after hearing comments made the jury following the conclusion of the original trial and her lawyer Brian Panish confirmed they were gathering information for an appeal.

He said: ''She isn't throwing in the towel. We can't give up until we gather all the information. Today is another chapter.''
