The internet is LOLing at Ariana Grande's ruthless nan

Ariana Grande launched her Dangerous Woman world tour over the weekend, and reserved a special place in the front row of her second show for her beloved grandma.

But we're not quite sure Nana was completely stoked....

Captured in fan-shot video Marjorie Grande looks bored, tired, and sometimes horrified by what's happening on stage at the Las Vegas show.

Later in the show, as Grande sang the line "Don't you know I ain't f**kin' with them good boys ... ain't you ever seen a princess be a bad b*tch?" her grandmother quickly covered her mouth with her hands in an apparent expression of shock.

Perhaps Ariana's songs are exactly Grandma's cup of tea! 

But there's no denying the pair still share a close bond.

Only weeks ago Ariana pushed her 'Nonna' in a wheelchair as they took part in the massive Women's March in Washington together.
