Brace yourselves, Khloé Kardashian and Lamar Odom fans! Life & Style has exclusively learned that the reality star is pregnant with the former NBA player's baby — though she's not exactly happy about it.

“A lot of people don’t know it, but Khloé and Lamar were still sleeping together in June,” an insider reveals, adding that “the timing couldn’t be worse” for the 32-year-old.

As followers of the duo know, Lamar, 36, recently got wasted before a flight to NYC earlier this month, and has been hitting up multiple strip clubs. But a baby won't change Khloé's opinion of him, the source says.
