The 'Keeping Up With The Kardashians' star is reportedly expecting her first child with her partner Travis Scott and the baby is thought to be arriving in just a few months time.
A source said: "They started telling friends a few weeks ago. The family has known for quite some time. She is really excited and so is Travis!"
Whilst another insider added to People magazine: "It is an unexpected but completely amazing turn of events that she could not be more excited or thrilled about. Everyone is overjoyed for her. This is the happiest she's ever been."
Kylie fuelled speculation she was expecting as of late by posting old photos of herself on Instagram or if she went for a new picture, opting for only chest and above pictures.
