She may be one of the biggest pop stars on the planet, but that doesn't mean that Ariana Grande gets away with swearing in front of her grandmother.

Marjorie Grande aka her 'Nonna', had a front row view of Grande's recent gig in Las Vegas last weekend, beside the pop star's brother Frankie and some other family members.

However, the family matriarch appeared pretty bored throughout most of the gig, and during one song which saw her granddaughter swearing, she is seen putting her head in her hands like only a Nonna can.

We'd hate to hear how she reacted after the whole donut-licking incident.
