Khloe delivered a baby girl early Thursday morning -- around 4 AM EDT -- at a hospital outside Cleveland ... according to our Kardashian sources. We're told the little girl does not have a name yet. Kourtney, Kim, Kris and Khloe's BFF Malika were by her side during the birth. Tristan Thompson was also there.
This is Khloe and the Cavaliers star's first baby together, but, of course, it comes smack in the middle of a tumultuous time for the couple.
TMZ broke the story ... Tristan cheated on Khloe back in October when she was only 3 months pregnant. As we reported, he was caught on video making out and motorboating 2 women at a hookah lounge outside of Washington, D.C. And just 5 days ago, he was seen taking a woman back to his NYC hotel.
