Kourtney Kardashian is pregnant with her second child
The 32-year-old star - who already has 23-month-old son Mason with her boyfriend Scott Disick - is "thrilled" to be expanding her family and providing a sibling to her first child.
She said in a statement to E! Online: "Scott and I are so excited to announce that we are expecting our second child and are thrilled to be expanding the love in our family."
Kourtney recently began a new web series entitled `Kourtney`s Mommy Blog` where she unveils what she has learned as a mother.
She has previously claimed she is never happier than when she is spending time with her son, and struggles to do things without him.
She said: "Unless I`m working, I can`t be away from him without feeling guilty. It doesn`t feel good or natural to be, so it`s a struggle.
"I don`t want to judge, but I`ve also met women who think it`s cool to be out or away from their baby, and I don`t get that. Every time I`m not working, he`s with me. Even on an airplane, he is with me even if the nanny is also on the plane. Any time I can have with him, I am lucky to have."
