Khloé Kardashian has welcomed a baby girl!

TMZ reports the reality star gave birth around 4 a.m. ET on Thursday at a hospital outside of Cleveland.

It is unknown if Tristan was there for the birth. He was playing at a Cleveland Cavaliers home game last night.

The baby news comes after her boyfriend Tristan Thompson was allegedly caught on video getting close to a woman at PH-D Lounge in New York City over the weekend.

Khloé revealed her birth plan on an episode of “Keeping Up with the Kardashians,” explaining that her doctor would fly to the midwest for the delivery.

When "Extra" spoke with her back in January, she said she was looking forward to holding her new baby. “It's very exciting, but so scary too." She added that having so many experienced moms in her life is a "gift and a curse," explaining, "Everyone wants to give you their advice, I'm like, 'Kourtney, you were the first one and no one gave you advice and you managed.'”

At the time, she was happy to have Tristan by her side. “He really is so sweet, he's been a blessing, and how excited he is makes me more excited."

This is Khloé's first child, and Tristan's second. His son Prince Oliver, with ex-girlfriend Jordan Craig, turned 1 in December.
