(CNN)Khloe Kardashian is now a mom of two.
The reality TV star and her ex-boyfriend, Canadian-American basketball player Tristan Thompson, have welcomed their second child via surrogate, a source close to Kardashian told CNN.
No name for the baby boy has been shared yet.
The former couple is also parents to a 4-year-old daughter, True.
The pair have had a tumultuous, on-and-off-again relationship marked by several cheating scandals.
In January, Thompson confirmed that he had welcomed a son with fitness model Maralee Nichols.
But Kardashian, 38, has been vocal about her commitment to co-parenting with Thompson and her desire to grow her family.
She documented her efforts to conceive a second child through IVF and fertility assistance on “Keeping Up with the Kardashians.”
