Ariana Grande performed in Las Vegas on Saturday night with her grandma and brother sitting right in the front row.<\/p>\n
Grande’s brother, Frankie, came decked out in Ariana Grande apparel and Snapchatted himself dancing and singing to all his sister’s hit songs. Marjorie Grande — known as “Nonna,” the Italian word for grandma — was not quite so thrilled. <\/p>\n

Nonna sat with her chin in her palm or her hands in her lap for most of the show, appearing a bit underwhelmed. Her expression quickly changed, however, when Ari launched into expletive-filled lyrics while performing “Bad Decisions.”<\/p>\n
Her grandma covered her mouth and looked stunned as her granddaughter sang, “Don’t you know I ain’t f***ing with them good boys?” and “Ain’t you ever seen a princess be a bad b***h?”<\/p>\n
