Keeping Up with the Kardashians star Khloe Kardashian is enjoying the single life. So much so that the reality TV star and mother of one recently said she's single but not available. Ahead of what appears to be a tense episode full of emotion, the show's latest preview features Khloe discovering a lie while reading through an advance copy of her ex-husband Lamar Odom's autobiography.

Last season on Keeping Up with the Kardashians, fans watched as Khloe's relationship with NBA player Tristan Thompson fell apart after multiple bouts of infidelity. On last season's finale, there was the cheating scandal heard around the world, when Kylie Jenner's BFF, 21-year-old model, Jordyn Woods, was reportedly caught kissing Tristan at a party in February. Khloe felt betrayed by her sister's best friend after she hooked up with her then-boyfriend and father to her 1-year-old daughter True Thompson. After Khloe called Jordyn a home-wrecker, Jordyn was then cut off from the Kardashian/Jenner family for good and hasn't been seen with Kylie since. Khloe credited the very public cheating scandal with tearing apart their family of three and hurting everyone involved.

Now, Khloe appears to be single and happy, but not available at the same time. The 35-year-old posted a quote on her Instagram Story indicating that she’s focusing on herself and enjoying her single status. “Being single doesn’t necessarily mean you’re available,” reads the quote. “Sometimes you have to put up a sign that says, ‘Do Not Disturb, God is working’ on your heart.” She also posted a second quote that implied how happy she is: “The universe gives me everything I want and need. Always has. Always will.” Her posts come after Keeping Up with the Kardashians teased an upcoming episode where her ex Tristan Thompson gifts her with a pink diamond ring. The teaser shows Scott Disick pointing out how the rock “looks fully like an engagement [ring],” while Khloe insists that it's not.

After she and Thompson called it quits for good following his hookup with Jordyn, Khloe revealed that she has since forgiven him for the sake of their daughter. Earlier this month, a source told People that it “seems Khloé has moments when she is toying with the idea of getting back with Tristan.” “Tristan has showed more of an interest,” the source said. “He seems to want more than co-parent with Khloé.” “Everyone thinks she deserves better,” the source continued. “But it seems Khloé needs a good distraction to fully move on mentally from Tristan. She needs to find a special guy, and so far, she hasn’t.” However, other insiders claim she has her romantic relationship with Tristan firmly behind her. “Khloé has showed over and over again how strong she is and how she is determined to move on without Tristan,” the source said. “Tristan still tries to manipulate her, but Khloé sticks with her gut feeling that he will never change and just can’t be trusted.”

In addition to the ring from Tristan, the episode of Keeping Up with the Kardashians also features Khloe upset with her mother Kris Jenner regarding her ex-husband's new book. While previewing Lamar Odom's new autobiography, Khloe caught her mother apparently lying about something. Khloe confides to her younger sister, Kylie Jenner, saying, "Lamar is writing a book. In the book, I found out that mom's lying to me." Fans are later treated to another preview showing Kris's reaction. "I'm trying to do damage control," the momager solemnly says, while footage shows her scrolling intently through her smartphone. A final preview shows Scott Disick say to Khloe, "She literally thinks you're gonna, like, come for her," to which Khloe quickly responds, "Guess what? I am."
