Kendall and Kylie's half-sister, Cassandra Marino
(daughter of Caitlyn Jenner
) is reportedly
expecting a son. If this news is true, he would be her third child. Cassandra already has two daughters, Isabella and Francesca, with her husband Mark Marino
However, Kendall and Kylie aren't super close to Cassandra, so they probably won't interact with her new child that much. That said, they'll still be the baby's aunts!
Are you excited for the new addition to the family? Sound off in the comments!
