Sources confirm to PEOPLE that the E! series was filming at the hospital, possibly for the forthcoming season 15. Kardashian, 33, is also dealing with the alleged infidelity of her NBA boyfriend Tristan Thompson, who was present for the arrival of his daughter.
Thompson, 27, is also dad to 16-month-old son Prince Oliver from a previous relationship.
“Khloé labored with [mom Kris Jenner] yesterday at the hospital. Tristan was there for the birth,” a KUWTK source told PEOPLE on Thursday. “He has practice today, but will spend as much time at the hospital as possible.”
The baby news comes two days after allegations that Thompson was seen kissing multiple other women and a source calling him “a serial cheater.”
On April 10, videos surfaced of the Cleveland Cavaliers power forward allegedly getting close to an unidentified woman at the PH-D Lounge in New York City over the previous weekend.

This is not the first time the arrival of a Kardashian baby has been broadcast.
The now-8-year-old son of Kourtney Kardashian and Scott Disick was the first KarJenner child welcomed into this world for KUTWK viewers to witness as Disick filmed from the delivery room. It was later broadcast during the season 4 finale in February 2010.
