Girl group Little Mix will kick off their Salute tour later tonight (May 16) and have now revealed a series of 'tour secrets' during a new interview. 

Speaking to Digital Spy about what their life on the road is like, the 'Wings' beauties opened up about pre-show rituals and tour bus etiquette, which revealed that songstress Leigh-Anne Pinnock isn't the shy retiring type at all.

Blonde bombshell Perrie Edwards explained that Leigh-Anne is definitely the loudest member: "Leigh-Anne is the loudest on the tour bus, especially when you're trying to sleep. You don't have to be (on your best behaviour)... enjoy yourself, love."

Jesy Nelson then opened up about the band's pre-show rituals, adding that they like to hang out together before hitting the stage and put their hands in while singing lyrics to their songs: "We have a song that we all really love the most, and then whatever that song is we'll put our hands in and (sing it)."

Nelson also admitted that she thinks Little Mix's new tour will shock fans: "Just some surprise entrances and a few surprise covers and some medleys. But you will get hunky men. I think everyone is just going to be shocked because I don't think it's what people are expecting."

The girls' tour begins this evening in Birmingham at the LG Arena and you can watch their video for 'Salute' here:
