(TMZ) -- Another day, another Kardashian pregnancy -- but this time it's Khloe ... TMZ has learned.
Multiple sources tell TMZ Khloe Kardashian is pregnant with her first child, and the baby daddy is her NBA star boyfriend, Tristan Thompson.
TMZ's sources say Khloe is three months pregnant. TMZ was told Khloe conceived naturally. So far, she doesn't know the sex of the baby.
This now makes for three expecting Kardashians. TMZ broke the stories ... Kim and Kylie are also expecting, and their babies should be delivered around the same time in mid-January.
Khloe and Tristan have been dating for one year, almost to the day.
Good news usually comes in threes -- unless Kourtney wants to get in on this too.
