The couple, who is closing in on two years of marriage, spent Monday evening at Justin Bieber's Purpose World Tour show at the Staples Center in Los Angeles.
Clad in a The Life of Pablo-themed denim jacket, the 35-year-old reality star let her dyed hair down as she posed for photos with the Grammy winner and her childhood friend, whom she said she went to her very first concert with 28 years ago.
The married pair got playful during Bieber's set as Kardashian serenaded her hubby with a rendition of "As Long As You Love Me." She documented the moment on her new Snapchat account.
As for West, he appeared to loosen up later on into the night when Kim videotaped him getting his groove on to "What Do You Mean?" while sporting a bleached denim shirt.
It seems the star of the show was equally a fan of his concert guest. Bieber took to Twitter to personally thank the rapper for his attendance.
"Shout out to one of my inspirations @kanyewest for coming to the show tonight," he tweeted. "Had to go big."
The "Famous" performer finished off the night on a high note, enjoying a late night game of ping pong with Los Angeles Clippers player Chris Paul.
