Has Khloe Kardashian's alleged pregnancy made her insecure?

According to a new report, the 33-year-old Keeping Up With the Kardashians star is concerned that her boyfriend, Cleveland Cavaliers player Tristan Thompson, could dump her and return to his former girfriend, Jordy Craig, who gave birth to his first child last year.

"[Khloé's] terrified Tristan will fall in love with Jordan all over again," a source told Life & Style magazine on October 19. "She lacks trust after being married to Lamar [Odom] and doesn't want to see history repeat itself."

As fans will recall, Kardashian and Odom parted ways in 2013 after rumors swirled in regard to his cheating and drug use.

Years later, after briefly reuniting with Odom in 2015, Kardashian began dating Thompson and shortly thereafter, it was revealed that Jordy Craig was expecting his baby. While the two were no longer together at the time her pregnancy was announced, they have continued to co-parent the child together.

"Tristan left Jordan for Khloé when Jordan was pregnant," the source continued. "Although Tristan has sworn he'd never be unfaithful to Khloé, in the back of her mind, she still worries."

They've been "arguing non-stop," the source said of Kardashian and Thompson.

"She's desperate for Tristan to put a ring on it, but the more she's pressuring him to walk down the aisle, the more she's pushing him away," the source revealed.

Meanwhile, Thompson's Cavalier teammates, including LeBron James, feel that their relationship has become a distraction to his game.

For example, James reportedly "feels basketball should be kept separate" from the Kardashians.

"Last season, players told Tristan they didn't want the Kardashians around. When Khloé sits courtside, it's annoying that the focus goes from the game to reality TV," a different insider noted.
