[WATCH] Ariane Grande's Grandma Looked Dismayed As She Sings Explicit Lyrics Live!

A video has gone viral showing Ariana Grande's grandmother disapproving look when the singer sang an explicit part of her lyrics during her Las Vegas live performance. Marjorie Grande, Ariana's grandmother, whom she also calls "Nonna" was videoed sitting with her head in her hands until the singer launched into the expletive-filled lyrics for "Bad Decision."

 The said video was recorded during Ariana Grande's Las Vegas concert on Feb. 4. The 23-year old singer gave her grandmother a VIP front row seat at her concert. However, "Nonna" was evidently shocked when her granddaughter sang about not 'f**king with them good boys' that she even covered her mouth, according to Pop Crush.

Ariana Grande kicked off her highly-anticipated "Dangerous Woman Tour" at the Talking Stick Resort Arena in Phoenix, Arizona, on Feb. 3. The pop singer wore a sexy Calvin Klein bra and mini skirt. It seems that Ariane opted for a very sexy performance as she later switched into another racy ensemble for her sexy performance. Although we all know that most Ariane Grande's songs are indeed very sexy and somehow contain sexual lyrics.

In addition, while singing her top hits, a video was being played in the background of the arena. Images were flashed reading "grounded," "playful" and "sexual." However, words reading "not asking for it" came up, it was obvious that this was Ariana's way of firing back at those who confused her sexual empowerment as "an invitation for disrespect."

Meanwhile, Ariana Grande shut down some bullies during the first night of her tour. Said judgmental persons reportedly dissed her after making it clear she did not take kindly to being objectified by a fan of her rapper boyfriend Mac Miller, 25, back in Dec. 2016, according to Teen Vogue.

The "Dangerous Woman Tour" by Ariane Grande is ongoing and will conclude in Italy on June 17.
