マイペース、マイ・スタイル！　～日本語がぺらぺらになるには～

かいこう‐いちばん【開口一番】
口を開いてものを言いだすとすぐに。口を開くやいなや。「―相手を批判した」

Lady on TV said something along the lines of 開口一番が「可愛い」でしたね when saying customers liked the free gifts (i.e. lady was complimenting the artist who made them, by reporting how customers called them cute)

First thing out of their mouths was "Kawaii"!
