Khloé Kardashian is pregnant, a source with knowledge of the situation confirmed to BuzzFeed News on Tuesday.

The baby will be the first child for Khloé. Thompson, 26, welcomed a son named Prince Oliver with his ex-girlfriend Jordan Craig in December 2016.

“Yes, Khloe and Tristan are expecting and they are absolutely thrilled,” a source tells PEOPLE.

“This isn’t something they were in a rush to announce to the whole world, and it’s only been in just the past week or so that they’ve felt comfortable telling most of their inner circle.

Khloé is the third Kardashian-Jenner sibling to currently be expecting a child.
