Khloe and Lamar's Family Issues Revealed On 'KUWTK'

Khloe Kardashian has been keeping quiet about her marital issues in the media and now fans will see that she also had a hard time opening up to her family.

Kardashian, the 29-year-old co-star of "Keeping Up With The Kardashians," is the subject of the upcoming episode of the reality television show when questions arise concerning her relationship with her husband. In a preview of the upcoming show Kim Kardashian, 32, asks her younger sister about what she is hiding.

"You are obviously trying to avoid something, and you're afraid of it," Kim tells Khloe in a preview of the show.

However, Khloe isn't quick to open up to her sister.

"Why are you guys so pushy," Khloe questions in a preview clip.

While Khloe has been forthcoming about her desires to have children with her free agent NBA player husband Lamar Odom, 33, she has also opened up about their fertility issues in the past. In the upcoming episode of the show, Khloe seems to have a defining moment in her fertility treatment process.

"I'm not ready to continue with fertility treatments," Khloe said in a preview of the show broadcast on E! Network.

In the show's preview, a narrator alludes to issues that Kardashian has opening up to her family.

"Some problems are just too big to share even with family," the narrator in the preview clip tells the audience.

Odom, 33, has made headlines in recent weeks for allegedly stepping out on his marriage and battling with a drug addiction that he allegedly only checked into a rehabilitation center for one day to treat. In a preview of the show, Kardashian makes it clear that everything may not be well with her husband.

"Lamar, are you ok," she asks in the show preview while on the phone with her husband.

Kardashian lets viewers know that she intends to keep certain things private, even from her family.

"There are some things that not everybody knows and me and Lamar are the only two people that do need to know that," she says in the confessional on the show.

While Kardashian once referred to herself as "Kardashian-Odom" on Twitter, over 8 million followers recently witnessed her drop her husband's last name on the social networking website along with Instagram and Facebook.
