Ariana Grande wore a Zac Posen ball gown to watch the Grammy Awards on TV.

The 'Thank U, Next' hitmaker had pulled out of attending the ceremony on Sunday (10.02.19) following a row with producers over her planned performance, but saw no reason why she shouldn't get chance to wear the stunning pale blue strapless gown and staged a photoshoot in her apartment.

Ariana - who paired the dress with a jewelled choker and her signature high ponytail - shared a number of images of herself in the dress on her Instagram account.

She captioned one post: ''when @zacposen makes u a custom gown it doesn't matter if you're singing or not... thank u (heart emoji).''

While the 25-year-old star wasn't at the Grammy Awards - which were hosted by Alicia Keys at Los Angeles' Staples Centre - she scooped the Best Pop Vocal Album for her record 'Sweetener' and used Twitter to admit she was still delighted to have won.

She posted: ''I know I'm not there tonight (trust, I tried and still truly wished it had worked out tbh) and I know I said I try not to put too much weight into these things .... but f**k ....... this is wild and beautiful. Thank you so much (sic)''

Ariana slammed Grammys producer Ken Ehrlich on Twitter a few days ago when she shared pictures of an interview he'd given in which he claimed she couldn't ''pull something together'' in enough time.

She wrote: ''i've kept my mouth shut but now you're lying about me. i can pull together a performance over night and you know that, Ken. it was when my creativity & self expression was stifled by you, that i decided not to attend. i hope the show is exactly what you want it to be and more.

''i offered 3 different songs. it's about collaboration. it's about feeling supported. it's about art and honesty. not politics. not doing favors or playing games. it's just a game y'all.. and i'm sorry but that's not what music is to me. (sic)''
