Khloe Kardashian Gives Birth to First Baby With Tristan Thompson

Khloe Kardashian has welcomed her baby girl!

The Keeping Up With the Kardashians star gave birth to her daughter with NBA player Tristan Thompson on Thursday around 4 am ET in a hospital outside of Cleveland, Ohio, ET can confirm.

“Baby and mom are healthy,” a source close to the Kardashians tells ET, adding that the little one is "beautiful" and does not yet have a name.

Khloe's sisters Kim and Kourtney, mom Kris Jenner and best friend Malika Haqq were with her in the delivery room.

The days leading up to the birth were a turbulent time for the couple, who welcomed their first child amid reports that Tristan allegedly cheated on Khloe with multiple women.

A source told ET on Wednesday that Khloe "is completely devastated" by the allegations, and that Khloe’s mother, Kris Jenner, recently flew to Cleveland "to be with her and support her in whatever she needs."

On Tuesday, after the first infidelity allegations surfaced, a source told ET that Khloe's family were all "rallying around her" during the tumultuous time, and that they tried to make sure Khloe focused on "having a healthy experience."

The source said that the allegations came as a shock to the Kardashian family, who "really like Tristan and have welcomed him into their family."

In the days leading up to her due date, before the allegations surfaced, Khloe spent her time keeping a low profile, relaxing at the couple's home in Cleveland and taking to Instagram and Snapchat to document the final days of her pregnancy journey.

The 33-year-old reality star has not shied away from baring her glowing pregnancy bod, sharing numerous snapshots of her baby bump in romantic snapshots with Tristan. On April 9, Khloe posted a touching photo of her and her shirtless boyfriend sharing a sweet kiss, which she captioned, "We are ready whenever you are little mama."
