The ?Complicated? songstress looked excited to be showing off her new collection of clothing and goodies, having enlisted the ?Keeping Up with the Kardashians? star to walk in the show.
After the shindig was over, Lavigne (who recently announced her engagement to Chad Kroeger) took to her Twitter page to share her gratitude for Jenner?s help.
Avril tweeted, “Thank u to @KylieJenner and all the beautiful models who rocked the @AbbeyDawn runway tonight!! Kick ass! (sic).”
Meanwhile, Kylie told press, “I love Avril. I love her; I love her clothes, so it was such an honor to be in [her show]. It was so much fun.”
