Kourtney Kardashian's son Reign begged her to 'say poop' into a microphone while she and Travis Barker were giving their wedding reception speech

• Kourtney Kardashian's youngest son Reign asked her to "say poop" during her wedding reception.
• Kardashian agreed, saying the word into a microphone before she and Travis Barker spoke.

In a silly moment during her Portofino, Italy wedding reception, Kourtney Kardashian Barker's son Reign asked for her to "say poop" into the microphone before her speech — and she humored his request.

Kardashian Barker and her husband, Travis Barker, shared behind-the-scenes footage of their Portofino, Italy wedding in a new Hulu special, "'Til Death Do Us Part Kourtney & Travis." That included plenty of clips from their wedding reception, including one silly — but heartwarming — moment between Kardashian Barker and her then 7-year-old son Reign Disick.

"Mom, say poop," Reign called out as Kardashian Barker and Barker stood poised to give a speech. Barker then looked at his wife expectantly, holding the microphone up to her mouth.

"Poop," Kardashian Barker said after a beat, prompting a childish cackle from the audience. "That was for Reign!"

The couple were married in a lavish, Dolce & Gabbana curated wedding ceremony held in Portofino, Italy and attended by their friends and family. The reception featured a number of surprises, such as renowned vocalist Andrea Bocelli and his son Matteo serenading the couple with a rendition of Elvis Presley's "Can't Help Falling In Love With You."

Kardashian Barker shares her three children – Reign, now 8, Mason, 13, and Penelope, 10 — with ex Scott Disick. During the ceremony itself, Reign served as a ring bearer for the couple, while Penelope was a flower girl. Barker's children Landon, 19, Alabama, 17, and Atiana de la Hoya, 24, were also part of the wedding procession.

"'Til Death Do Us Part Kourtney & Travis" is now streaming.
