Little Mix talk show nerves

Perrie Edwards found supporting Demi Lovato nerve-wracking.

Perrie, along with Little Mix bandmates Jade Thirlwall, Jesy Nelson and Leigh-Anne Pinnock, were with Demi on her Neon Lights tour.

The British girl group are making a big name for themselves across the pond, but were initially apprehensive about performing stateside.

"It was incredible," exclaimed Perrie on UK TV show This Morning. "But we went over there and we were really nervous because we thought, 'Right, they're not our fans, they're not going to know who on earth we are.' And then the first night we just heard, 'Rahhhh,' when Little Mix were announced and we were like, 'Oh my gosh,' it was crazy, like we just couldn't believe it."

"Everyone knew the lyrics to our songs, the crowd was just mad. It was amazing," echoed Leigh-Anne.

The four piece are now gearing up for their very own arena tour, which will see them take in dates in the UK and Ireland from May.

"It's [a] huge [responsibility], we're just so excited aren't we? Because obviously we've done a theatre tour and we've supported arena tours but now it's our own we just can't wait to put on a big show.

"We're so passionate about it. We're already talking about outfits and this and that and we're just getting into it and we so can't wait," Perrie gushed.

The girls are also busy promoting their latest single Word Up! A cover version of the 1980s Cameo hit.

The single is in aid of the charity work undertaken by Sports Aid, which meant the girls got to go to Africa to experience first-hand how money raised can help those in need.

"Oh goodness it was so hard hitting. Like obviously you see it on TV all the time, like you see the adverts, then you go there and see it in the flesh and we just couldn't believe it," Jade explained.
