Fifth Harmony star Normani Kordei says she often has to "mentally psych" herself up for songs in the second half of the group's set.

The US quintet have an energetic live show and it often has a tiring effect on the ladies.

Speaking to Digital Spy, Kordei said she usually has to hype herself up for the tune 'Big Bad Wolf'.

When asked if there is a song that she dreads performing, the singer said:

"Well I wouldn't say there's a song I dread performing, but definitely when we get to the second half of the show we're already super tired and winded.

"So by the time I get to 'Big Bad Wolf' I'm just like, 'I just want to get through this!' I have to mentally psych myself up."

Asked what her favourite song to perform is, bandmate Ally Brooke Hernandez added:

"One of my favourites to perform is 'That's My Girl'. It's the opener of the tour and it's very powerful. It's very strong and the choreography is great.

"The band is amazing and they really bring the song to life. I just love it. But also, 'Gonna Get Better' is one of my favourites."
