Watch: Little Mix perform on 'X Factor USA', mock Rebecca Ferguson + she responds...

Some women are never destined to be best friends with the ex-girlfriends of their current beau. Therefore, it's certainly not a crime to laugh at a bitchy joke made about that very ex-girlfriend, even if it's with catty intentions. I think we may have a "situation" here.
Rebecca Ferguson has had nothing but good things to say about Little Mix and even stated that she considered herself a fan in a previous interview. Just this week, band member Jesy Nelson was seen mocking Rebecca Ferguson's new single 'I Hope' in a behind-the-scenes video from The X Factor USA. It all looked innocent - until Perrie Edwards and Jade Thirlwall pissed themselves with laughter at her impression. When Rebecca's street team brought this video to light telling the singer that they were taking the piss, her semi-sincere response was: "so nice to see they had time to pay tribute to my single".

For those not in the know about One Direction's love life, Zayn Malik dated Rebecca a few years ago and now he is engaged to Perrie. All three of their careers were birthed from the UK's X Factor. But it seems no love was lost. Check out the girls mocking Rebecca, and their performance of 'Move' on X Factor USA inside.
