WATCH: People are losing it over clip of Kendall Jenner trying to climb stairs at Kourtney’s wedding

"The things we do for fashion."

Kendall Jenner had a bit of an awkward moment at her sister Kourtney Kardashian's wedding this weekend - when she almost couldn't make it up a flight of stairs. Kylie Jenner took to her Instagram Stories to share a hilarious video of Kendall slowly waddling up the steps in a skin-tight Dolce & Gabbana gown. Kylie could be heard laughing hysterically as she recorded her sister's struggle, before saying: "Oh s**t, these stairs are crazy." https://www.instagram.com/p/Cd4BN3VJoYS/ "I always wondered how they could walk with that kind of dresses, now I know," one person wrote in the comments. "The things we do for fashion," another added. Later, Kylie shared a video of the two dancing at the reception, saying in the caption that Kendall was her "cucumber girl" - a reference to viral video that surfaced a few weeks ago showing the model confused about how to chop up a cucumber. Kourtney tied the knot with Blink-182 drummer Travis Barker in Portofino, Italy, on Sunday after welcoming family and friends to the resort town days earlier. The family kicked off the celebrations with a pre-wedding lunch and rehearsal dinner. The wedding weekend then ended with a huge party that included some familiar faces such as Machine Gun Kelly, Megan Fox, and Mark Hoppus.

Kourtney wore a white minidress and gorgeous elaborate veil at the wedding ceremony, but later changed into a sleek gothic black version of the dress with a shorter veil for the reception.

The 43-year-old's ex-boyfriend, Scott Disick was not in attendance at the wedding. The wedding was the third time the couple have gotten married. They had their first wedding in an intimate Las Vegas ceremony after the Grammy Awards and last month, they made things legal in Santa Barbara, California. Travis proposed to Kourtney back in October 2021.
