Fifth Harmony prepare for their X Factor UK debut: "The pressure is kind of on"

X Factor US alumni Fifth Harmony are gearing up for their televised live performance on the UK edition of the talent show.

The five-piece girl group will perform on the Sunday results show on December 7.

Speaking to The Huffington Post UK about Fifth Harmony's upcoming appearance on The X Factor, Dinah-Jane Hansen said:

"They told us being on The X Factor was like the VMAs - only the big-time people perform on there."

She went on: "I feel like going out there, there is some pressure because we're performing in front of a new crowd - and it's where X Factor originated so we need to make sure we're on point."

Dinah also revealed the group's nerves about singing in front of the show's judging panel:

"Whenever I perform in front of Simon it feels like the first audition every time. I go back to how I felt the first time I ever saw him, and I get butterflies every time... The pressure is kind of on, we're performing in front of two legendary girl group singers so it's like, 'I gotta make sure I whip my hair right and hit the notes'."
