Perrie Edwards and her Little Mix bandmates couldn’t help but burst into giggles on Saturday, when a fan called Zayn Malik a ‘b***h’.

The band were performing single ‘Shout Out To My Ex’, when a fan interrupted Perrie’s verse to shout: “Zayn Malik is a little b***h", much to the girls' amusement. 

The audience reacted with stunned screams, but the girls erupted into laughter, with Jade Thirlwall even appearing to give a thumbs up for the comment.

Perrie and Zayn ended their engagement last summer and the break-up has served as inspiration for many of the tracks on Little Mix’s chart- topping album Glory Days.

But while the girls are used to laying their personal life bare on their records, they’re reportedly set to open up even more on an explosive “tell and show all” TV documentary.

According to The Mirror, the band are currently working on the project and are looking to land a deal with UK broadcasters to air the documentary next year.

Jesy Nelson told the newspaper: “We are in talks at the moment. We really want to do a ­documentary as we feel people do not know much about us.

“They know our songs and have seen us perform but they don’t know our personalities, so we would love to do a documentary. We want to get someone to follow us around on this whole tour for a whole year.”
