The youngest sister of the Jenner-Kardashian clan has been a big Gwen Stefani fan for quite some time and she recently posted a throwback video on her website to show her subscribers just how long it has been.

The 18-year-old posted the video on KylieJenner.com, which showed her on stage with the singer when she was just 8 years old. Moreover, Jenner was lucky enough to sing a line of the hit “Hollaback Girl” with Stefani.

“My first concert ever was Gwen Stefani in 2005!” Jenner wrote on her site. “During the ‘B-A-N-A-N-A-S’ part of ‘Hollaback Girl,’ she brought a bunch of girls onstage to sing with her. One of her backup dancers put me on his shoulders and then Gwen put the mic in front of me to sing. I was so little! But it was cool because I ended up going on Gwen’s concert DVD, 'Harajuku Lovers Live.’”
