Kim Kardashian models a bra and briefs at home to promote her SKIMS empire

Kim Kardashian is a boss lady and she wants the world to remember that as she is in the middle of a difficult time in her personal life.

On Wednesday the 40-year-old entrepreneur looked sensational as she modeled a pair of SKIMS lingerie while looking in a mirror at her $60M home in Hidden Hills, California. She also owns KKW Beauty and KKW Fragrances making her worth $1B.

This comes after claims her estranged husband Kanye West changed his phone number and will only talk to the KUWTK star through security personnel.

The small screen star looked incredible in the bra and undies with a robe over her shoulders as she seems to be in the best shape of her life thanks to working with her personal trainer Melissa Alcantara,

She added white socks that highlighted her toned legs. Her hair was pulled back tight and worn in a long braid that fell down her chest and toned tummy.

The siren was standing on a concrete floor with racks of clothing all around her.

She and her ex are reportedly no longer on speaking terms after the rapper ‘cut her off’ when their divorce papers were filed. 

The couple, whose split was revealed in January before Kim filed for divorce last month, are said to be only communicating through security after Kanye, 43, changed his number in his cut-off of Kim.

Despite the latest development, sources have confirmed that Kim is not cutting off his communication with their four children, North, seven, Psalm, five, Chicago, three, and Psalm, 22, month, with various nannies helping make the co-parenting easier.  

Insiders told Page Six: ‘Even before Kim filed for divorce, Kanye changed his numbers and said, “You can contact me through my security”. Despite this, she trusts him around the kids. He loves them and is seeing a lot of them.’

The source went on: ‘She leaves the house and he arrives and hangs out with the kids. They have an army of nannies so the transition is easy.’

MailOnline has contacted Kim and Kanye’s representatives for comment. 

The couple are believed to have signed a prenuptial agreement, and TMZ claims neither party is contesting the terms of the document.

Kim’s divorce documents were filed by Laura Wasser and reportedly don’t list a date of separation, instead claiming the date is ‘to be determined’.  

The couple were reported to have hit a rough patch in their romance late last year, and it was claimed last week that Kim was keen for Kanye to keep a constant presence in his children’s lives. 

A source had said: ‘He still wants to play a huge role in their lives and Kim would never discourage that… He is no longer living at the house with Kim and the kids. When he sees the kids, he meets them elsewhere.’

It was also reported the couple were in no rush to legally terminate their marriage, but had separated in private.

The insider added: ‘Kim already feels like she is divorced. They are at a standstill currently and neither of them are pushing [to make the split official]. At this point in time, there is no rush for the paperwork to be finalised.’

They cited ‘irreconcilable differences’ as the reason behind their split. They also confirm that Kim has asked for joint legal and physical custody of their kids.
