E! News has confirmed that Khloe rejected Tristan’s proposal in December 2019, but the pair secretly got engaged around February 2021. They remained fiancés until news broke that Tristan was facing a paternity lawsuit after fathering a baby with Maralee Nichols.
Maralee welcomed the child, a baby boy named Theo, in December 2021. Roughly seven months later, multiple sources confirmed to E! News in July that Tristan and Khloe were expecting their second child together via surrogate.
As a source close to Khloe explained in July 2022, Khloe and Tristan are strictly co-parents, adding, “The baby was conceived via surrogate before it was revealed to Khloe and the public that Tristan was having a baby with someone else in December.”
