Keeping Up With The Kardashians: Kourtney shows off her enviable figure in a black bikini as she reveals she has a tendency to 'procrastinate'
There was a lot of tension on Sunday's Keeping Up With The Kardashians.
And that included a little bantering between Kourtney Kardashian and her younger sister Khloe. The two were arguing over a fitness line as they sat by Kris Jenner's massive swimming pool in Hidden Hills, California.
The 38-year-old mother-of-three looked toned in a black two piece as Khloe, who is reportedly pregnant with her first child, covered her midsection by laying on her stomach.

Khloe looked beautiful with her blonde locks falling down her back and rose-tinted sunglasses on.
The reality TV queen also showed off long red nails that appeared sharp.
While Kourtney seemed to be enjoying white wine, it didn't look like the Strong Looks Better Naked author was in the mood for spirits.

And the mood was tense.
Kourtney and Khloe planned to launch a fitness fashion line together, with Khloe putting on hold a line she had ready for Good American.
'I love working with Kourt, I love that she's passionate and excited about something, so I'm fine tabling my Good American line for a minute,' she said.
But then they started bickering as Khloe clearly thought Kourtney was not doing enough to get their project up and running.
![Claws: The reality TV queen also showed off long red nails that appeared sharp](http://web.archive.org./web/20171219233856/http://i.dailymail.co.uk/i/pix/2017/12/18/19/476BD05400000578-5191923-image-m-15_1513623724245.jpg)

When she finally pulled the plug and told Kourtney she was instead going back with her line with Good American, Kourtney surprised her by smiling and saying: 'Go for it girl. I'm not the fastest moving person, and I know that I procrastinate,' she admitted.
'I know that I don't follow through - that's why I need a partner that does those things and pushes me.'
Khloe was then seen in a sexy photoshoot for her line, wearing a skin-tight body suit, saying proudly: 'I don't want to go backward. I really love where I am as a businesswoman right now. I love that my opinions matter and that I'm able to make such strong executive decisions right now.'

Chilling at mommy's house: They were relaxing at Kris Jenner's mansion in Hidden Hills
On Monday Kourtney did not address the issue, but rather shared a look on kourtneykardashian.com at the spacious bedroom and bathroom she reserves for VIP guests.
In an entry simply titled 'My Guest Room At Home,' the star shared two photos by Burke Doeren.
The ex of Scott Disick began: 'I love having friends come stay with me at my house.
'I didn't want my guest room to be an afterthought and really wanted to make it a comfortable space with a cool vibe,' the cover girl explained.
'My decorator, Martyn Lawrence Bullard, helped me find modern pieces mixed with cozy linens.'
Kourtney, who has appeared in Architectural Design, added: 'Martyn designed this custom-upholstered bed in a modern taupe velvet.
'The vintage Moroccan rug from Mansour Modern covers the whole room and makes the space feel extra cozy. Obviously, bedding is key, so I use the same super-soft linens throughout my house from a company called Legna.'
![Nice look: Kourtney shared a look at the guest room inside her Calabasas mansion in a post shared on Monday to her pay site](http://web.archive.org./web/20171219233856/http://i.dailymail.co.uk/i/pix/2017/12/18/18/476F441B00000578-5191829-image-a-100_1513622089065.jpg)

And the star did not mind going into great detail.
'These bedside tables from Rose Tarlow were my mom's that she gave to me.
'I always put out glass carafes with filtered water on these tables so my guests can stay hydrated and have water handy throughout the night.
'Behind the bedside tables, I added custom-framed mirrors to add dimension to the space and also to pick up some of the lighting from the lacquered table lamps.

'The 1965 black-and-white photo of Edie Sedwick and Andy Warhol above the bed is by photographer Steve Schapiro and from the Fahey Klein Gallery.'
The mother to Mason, Penelope and Reign then said: 'Lighting is so important to make any room comfortable, so I wanted to make sure it was addressed for the guest room, too!
'The matching black lacquer Atollo table lamps from Oluce are both on dimmers so the light can be adjusted from bed. The industrial-style Edison chandelier is also on a dimmer and has cool vintage-style lightbulbs.'

Kourtney was last seen on a date with Younes over the weekend; she also stopped by Disneyland to enjoy the holiday decorations.
And she has been appearing in the Kardashian family Christmas card.

Her sisters also added to their websites.
Khloe talked about her favorite Christmas gifts on khloewithak.com.
'I know how hard it is to find good gifts for my family members (read about my struggle here), so when I receive something that really touches me ... honey, I'm impressed. Check out the sweetest Christmas gifts I've received from my sisters!' said the reportedly pregnant star.
'Kylie - My lil' cutie got me a personalized choker one year and I love it. For her 20th birthday, I had one made for her that said "BabyGirl" (my nickname for Kylie),' she said.

Kim gave her 'something that Keeks had that I was totally loving, so she bought me one, too. It was so nice and selfless of her—and now we're twins!'
Kendall bought all four sisters matching sister necklaces which she found 'so special. 'She added: 'I still treasure it.'
Kourtney gave her a portrait of Marilyn Monroe, 'one of my all-time favorites.'
She added: 'It was her photo shoot with Lawrence Schiller, who was one of my dad's best friends.'
Khloe also said 2017 was incredibly because of Tristan, her birthday party, time with her nieces and nephews and the success of Good American.

And Kim on kimkardashianwest.com talked holiday traditions.
'The holidays are such a special time of the year. I’m especially grateful for our large family and all the holiday traditions we’ve continued over the years. Passing these traditions down to my kids is really important to me and it just makes me realize how blessed we all are to be such a close family.
'Before the holiday season even begins, we all go to Aldik Home to pick out the most incredible Christmas decorations. I swear, every year someone tries to steal my decoration ideas! I’ve started keeping my plans to myself so everyone is surprised. I can get competitive, lol—we all can! And, a lot of us love to use Jeff Leatham to help us bring the most incredible holiday decor to life.

'Next on our holiday traditions list is designing our family Christmas card. This year, we kept the look simple with denim and white tees. I love how it turned out! Our theme was 25 Days of Christmas, so we’ve been revealing a picture every day leading up to Christmas Day.
'Before Christmas, we also always have a gingerbread house decorating party at Kourt’s. She invites close friends and family over so that the kids can all be together.
'My mom's annual Christmas Eve party is probably everyone’s favorite night of the year. It’s all our closest family and friends celebrating the holidays with a night of food, fun and dancing. Everyone gets glammed up and we have the best time. My mom is the ultimate host and no one comes close to her decorating skills.

'At the Christmas Eve party, we see the same Santa that we’ve had since we were kids. He is honestly the perfect Santa! It’s really special that something I experienced in my childhood is now a part of my kids' childhood. We also have a photo booth at the party. You know our family loves a good photo booth!
'On Christmas morning, we all wear our matching pajamas when we open presents at Kourtney's house. Each year, we get different pajamas.
'Over the years, it’s become a tradition that each family member has their own wrapping paper so that you know who the gift is from—it’s a fun representation of their style. In previous years, Kanye and I went with matte black wrapping paper with a black ribbon. It’s fun to give gifts that personalized touch.'
