Kourtney Kardashian and Travis Barker finally tied the knot on Sunday, May 15.

Many people wondered where her children were after she became Mrs. Barker.

Tensions were already high when the Poosh creator discovered her children had not been invited to Travis' proposal, but did Mason, Penelope, and Reign also skip their mother's wedding?

Scott Disick, Kourtney's ex and the father of the three children, uploaded photos of the three youngsters as the 43-year-old reality star and the 46-year-old drummer who made news by making their union official at a Santa Barbara courthouse on Sunday.

The "Flip It Like Disick" actor captioned a photo of himself and his youngest son sunbathing, "Living the dream."

A few hours later, Scott released a video of Mason, 12, and Penelope, 9, goofing about on Instagram Stories, tagging the footage "Pushin P."

Kourtney and Travis married on Sunday, with Kris Jenner's mother, MJ Campbell, in attendance.

Travis' children, Landon and Alabama, were allegedly present.

Someone else stated, "I feel terrible for those youngsters. Imagine missing your mother's wedding."

Penelope's response to Kourtney's engagement was stunning, with viewers witnessing her fall into tears via FaceTime as the mom-of-three told her only daughter about her engagement.
