Kourtney and Travis' pregnancy announcement was pretty epic, too.

On June 17, Kourtney and Travis took to Instagram to officially announce they're expecting their first baby together. A clip showed Kourtney jumping up and down and holding a sign that read, "Travis I'm pregnant" at a Blink-182 concert in Los Angeles. As E! Online reported, the sign was a callback to Blink-182's music video for "All the Small Things."

Kourt has already shared a few baby bump photos.

In addition to the pregnancy reveal, Kourt has already posted a handful of photos showcasing her growing bump. "Overwhelmed with gratitude and joy for God’s blessing and plan," she wrote via Instagram alongside a carousel of images. One picture showed Travis gently tapping on her belly with his drumsticks while another featured Travis kissing her bump.

Neither Kourtney nor Travis have shared when the due date is for their baby. The Poosh founder did, however, post a full-body mirror selfie while wearing a bikini — and her growing bump was front and center. Hopefully, Kourt keeps sharing updates about her pregnancy journey so fans can continue following along. (We can't wait to see pictures from her baby shower!)
