Khloé Kardashian and Lamar Odom are officially on track to be divorced, and now, surprising new details behind the reality star's major decision have come out.

According to TMZ, Khloé chose to end their marriage for good because she wants to have kids.

Sources connected to the former couple said she recently sat Lamar down and explained everything to him, telling him the only way she can have a family is if she was completely single again.

Khloé allegedly told Lamar she would postpone their divorce until he was well enough to run his own day-to-day life, following his nearly fatal incident. Now that she believes he's at that point, she is ready to get the ball rolling. Initially, rumor had it that Khloé felt betrayed by Lamar because he appeared to be slipping back to old habits — he was spotted ordering drinks at bars on two separate occasions in recent weeks — but actually that wasn't the "last straw" the media made it out to be.

TMZ says Lamar was completely understanding of Khloé's decision and they both have decided to remain friends.
