Twitter wars: Ariana Grande and her mom Joan blast Piers Morgan over his comments on Little Mix and its singer Jesy Nelson

Piers Morgan's feud with 'Little Mix' has now caught the attention of Ariana Grande and her mother Joan Grande. Both of them have harshly criticized Morgan's insensitive and mean comments towards the girl band's new album. Morgan posted a tweet accusing the band of copying their promotional art from the 'Dixie Chicks', he then went on to criticize Jesy Nelson, a member of the band, for the picture she uploaded in just her underwear. His tweets read, “Hey @LittleMix – when are you going to admit you stole this idea from @dixiechicks?,” after which he commented on Jesy saying, “Sultry? She looks ridiculous. Ask her to put some clothes on (if she has any…) & apologise for calling me a tw*t.” Nelson, earlier in the week, called Morgan a t**t because he accused the band of using sex and nudity to sell their albums.
