Kim Kardashian is planning a post-pregnancy weight loss DVD.

The reality TV star is six months pregnant with her first child with rapper Kanye West and already looking at signing a big money deal to slim down after the birth.

A source told the Daily Star newspaper: ''Kim can't wait to squeeze her famous butt back into her trademark skinny jeans.

''She's been talking to various big companies about a bootylicious workout DVD. In true Kim style this would be sexy latex cat suits and lashings of make-up for a ghetto style hip-hop work out.

''Although Kim loves being pregnant, like most women she has struggled with her changing body shape.

''A work out DVD would be the perfect incentive for her to shed those extra pounds and inspire others.''

Meanwhile, the 32-year-old star has been dealt a blow in court when a judge refused her request to move the start date of her divorce trial from estranged husband Kris Humphries from May 6 to May 3.

In court documents seen by RadarOnline.com, Kim's lawyer, Laura Wasser ''respectfully requests the trial start one day earlier... and that there be no trial on May 6 due to [Kim's] unavailability. Kim Kardashian has a previously scheduled engagement in New York City on May 6.''

However, the judge sided with Kris' lawyer, Benjamin Johnson, who argued that ''Counsel for Petitioner Kimberly Kardashian specifically requested the May 6 trial start date back in February.''
