Little Mix's Leigh-Anne Pinnock's costly room service blunder

Little Mix's Leigh-Anne Pinnock splurged expensive food when the group first started out, without realizing she'd have to foot the bill.

The girl group formed on U.K.'s The X Factor in 2011, winning the singing competition and releasing their first album, DNA, the year after. While the girls can afford to live like queens now the same couldn't be said for their early days, especially when they were expected to pay their own way.

"When we first started, Perrie (Edwards) and Jade (Thirlwall) lived in Newcastle, but we had to be together so we stayed in this fancy hotel in London," member Jesy Nelson, 25, told The Guardian newspaper.

"These were the times when Leigh-Anne was really naive to it all and she thought everything was free. So she literally ordered the most expensive thing on the menu and the next day her bill was so ridiculous she was like, 'I can't pay that!'"

A similar incident happened when the group browsed Topshop while they were still contestants for The X Factor, racking up $1,860 worth of clothes when they were actually given a limit of $120.

As the group grows in fame, the Shout Out to My Ex singers still remain down to earth and put their fans first. This means they rarely take themselves seriously, with Perrie admitting they can often be "daft" when they're together, but she hopes this outlook encourages their younger audience to stay true to themselves too.

"What we stand for is making people feel good about themselves," she added. "That's what we love about people looking up to us. Obviously, don't copy everything we do (laughs)."

"We have this crazy, weird connection where we're all nutters," Leigh-Anne, 25, chimed in. "Some of our friends get it, but what we have as a four is just amazing."
