Khloé Kardashian and her ex-boyfriend Tristan Thompson will welcome a second child via surrogate, a representative for Kardashian told CNN. The former couple are parents of 4-year-old daughter, True

"We can confirm True will have a sibling who was conceived in November. Khloé is incredibly grateful to the extraordinary surrogate for such a beautiful blessing," the representative said.

In recent years, Kardashian has been open about her desire to grow her family. Her efforts to conceive a second child through IVF and fertility assistance were documented on "Keeping Up With the Kardashians."

While Kardashian and Thompson have had a tumultuous romantic relationship that ended in December, they communicate as co-parents. Thompson, a forward for the Chicago Bulls, is also the father of two young sons from other relationships.

Kardashian and the 31-year-old basketball player already share a four-year-old daughter named True and have had an on-off relationship since 2016.

"We can confirm True will have a sibling who was conceived in November," Kardashian's representative said in a statement on Wednesday.
