ET Canada can confirm the 33-year-old reality TV star gave birth to her first child True Thompson, with Canadian Cleveland Cavaliers NBA player Tristan Thompson, at a hospital near Cleveland, Ohio.

According to TMZ Thompson was by Kardashian’s side for the birth of their daughter.

Entertainment Tonight reports that Khloe’s mom Kris Jenner also recently flew to Cleveland to be with her daughter for the birth and to “support her in whatever she needs.”

After the momager tweeted a W magazine repost of her younger daughter Kendall Jenner saying “baby” three times, with a message of congratulations for Khloe: “BLESSED!!! When three of your sisters give birth in under a year. Congratulations to Khloe Kardashian on welcoming another girl to the KarJenner clan.”

Her older sister Kim, 37, took to Twitter Friday to gush over the adorable little one.

Kim welcomed daughter Chicago West via surrogate on Jan. 15, 2018, and 17 days later younger sister Kylie Jenner gave birth to her first child, daughter Stormi on Feb. 1.

It’s been a rocky week for Kardashian and Thompson, after videos emerged of the NBA player allegedly cheating on the star while she was pregnant.
