A bid by Martha Stewart, the high-profile US homemaker, to get out of house arrest early has failed.

She has already served five months in jail for her role in a share scandal, and was released in March to start her five-month house arrest term.
She had asked to be resentenced after federal sentencing guidelines were ruled advisory rather than mandatory.
But the judge said she would have imposed the same prison sentence even if guidelines had been advisory before.
"In my opinion, the sentence I imposed was particularly needed to reflect the seriousness of the offence, to promote respect for the law and to provide just punishment," US District Judge Miriam Goldman Cedarbaum wrote.
Home on the ranch

Still, Ms Stewart will be spending the remainder of her house arrest term in the relative comfort of her large ranch, 40 minutes outside New York.
She also gets 48 hours a week when she can engage in business activities away from the ranch. But the judge did not expand this to 80 hours as she had hoped.
Ms Stewart's problems began when she sold shares in drugs company ImClone ahead of regulatory difficulties with its cancer drug.
She and her former broker Peter Bacanovic were subsequently convicted of conspiracy and lying to authorities over her share sale.
However, her future prospects look good with a couple of TV series in the pipeline, and a TV film being made about her life.
She is also paid handsomely to provide creative input to her company, Martha Stewart Living Omnimedia.
