The brood's broadening: Khloe Kardashian is reportedly pregnant, and the news comes just days after a report claimed her sister, Kylie Jenner, is also pregnant.

According to TMZ, Kardashian and her boyfriend, NBA player Tristan Thompson, are expecting. The site says Khloe is three months along and that she conceived naturally. So far, the couple doesn't know the sex.

Kardashian and Thompson have been dating for one year.

TMZ reported that Kylie was pregnant on September 22, and that she "began telling friends earlier this month at the Day N Night Fest in Anaheim.” The site said she and the child's father, Travis Scott, are expecting a girl, and that Jenner has been sharing exclusively older pictures of herself on Instagram as to not alert followers to her pregnancy.

Page Six claims that the Kardashians plan to confirm the pregnancy news soon, ahead of E!’s Keeping Up With the Kardashians 10 year anniversary special.
