TMZ reports that the Kardashian is three months pregnant and conceived naturally. The NBA athlete and reality show star began their whirlwind romance just about a year ago to the date. 

The development would come a few days after Khloe's half-sister, Kylie Jenner, 20, was revealed to be pregnant with her first child, as well. The father is reported to be boyfriend of five months, rapper Travis Scott, and she's allegedly five months along with a baby girl. She's due in February.

Khloe and Kylie's older sister, Kim Kardashian, is also reportedly expecting a child -- her third, a girl, via a surrogate. She and husband Kanye West are expecting the child in January.
