The music mogul is going head to head with the Woman Like Me girlband

Simon Cowell and Little Mix are in a very public spat, with both in the process of searching for bands in their new talent shows.

Simon is bringing X Factor: The Band to ITV and the former X Factor winners are fronting Little Mix: The Search on BBC.

And now, Simon has taken their war a step further by calling the Black Magic girlband’s singing competition better suited to his X Factor rejects.

According to The Sun, while rejecting a contestant from X Factor earlier this week, he quipped: “Little Mix are doing a show next year. You should apply. Tell them I sent you.”

A source added: “It was obviously a real dig at the girls’ show. there is a proper feud.”

Little Mix – made up of Jesy Nelson, Leigh-Anne Pinnock, Perrie Edwards and Jade Thirlwell – left Simon’s label Syco last year after a dispute, and then they announced they’d be launching Little Mix: The Search, a singing contest to find a new group, on BBC1 early next year.

Clearly annoying Simon, he then pettily scrapped plans for an All Star version of X Factor and instead launched a competing show, X Factor: The Band.

It comes after Little Mix underwent a seriously epic make over in honour of their first ever Christmas single.

Spreading the merry news, video and pics of cartoon versions of the X-Factor stars dressed as elves were shared on Instagram.
