Kourtney Kardashian is not the only one who is happy and excited about her third pregnancy, but her joy is shared by her two kids too. The reality star is being helped by her two children Mason, 2 and Penelope, 4 to finish the baby nursery of her third child in her new $8.5 million home in Calabasas, California. The eldest of the Kardashian siblings is expecting her third baby with boyfriend Scott Disick and is currently in the phase of nesting.

The 35-year-old, who has a penchant for interior designing and doing up homes, is almost on the verge of finishing the nursery for new baby, reveals US Magazine. "Mason loves spending time in the nursery with his mom and is helping decorate. It's almost finished," a source close to the reality star reality revealed to the magazine.

The reality star, who is spotted in stylish maternity dresses, was earlier suffering from morning sickness in her first trimester because of her pregnancy, but her health has started to improve a bit now. The soon-to-be mommy swears by her routine that also involves healthy eating and taking a nap in the afternoon.

Meanwhile, there was speculation in the media that Kourtney and her partner Scott Disick are on the verge of break-up. Disick was reportedly not very happy to hear the news of his girlfriend's third pregnancy and was also spotted looking for apartments, Examiner reveals.

During the latest season of "Keeping Up With The Kardashians," Kourtney revealed the news of her pregnancy to Scott quite late and he clearly looks pissed off with her. He even said that Kourtney is "suckering him" into more kids.

The soon-to-be-mom then defends herself by saying she did not have the courage to tell Scott about the pregnancy, because she was worried about his reaction. But Scott is convinced that Kourtney lied to him and purposely hid the news from him. He even shows his annoyance by spending the night out, the episode of KUWTK revealed.

The father to Mason and Penelope was reportedly looking at a very small apartment that only had one bedroom in it. In the past, he was also kicked out by Kourtney from their rented apartment in the Hamptons because of his excessive drinking and partying habits.
