The news comes after a video surfaced online showing Khloe's baby daddy making out with two women at a club.
She was said to have delivered the child in the early hours of Thursday, April 12, 2018.
This is Khloe and Tristan's first child together.
The news comes after a video surfaced online showing Tristan making out with two women at a hookah lounge outside of Washington D.C.
The incident with the women was said to have occurred back in October 2017 when Khloe was only three months pregnant.
Just five days ago, Thompson was reportedly seen taking a woman back to his New York City hotel.
Khloe and Tristan have been dating for well over a year.
