Blonde Electra didn't feel nervous about their X Factor performance as they've performed for rapists in the past.
Ruby and Jazzy King confessed the series didn't scare them as they've put on shows for prison inmates.

Jazzy added: "We sang for about 200 lifers. They were all rapists and murderers."
The blondes also were forced by their father to sing to members of their parents' strict cult Children of God.
"Our parents met in a sex cult but left in 1991 and dad formed his own little cult, not sexual, but just as crazy. We had a very strict upbringing.
"He formed a little Christian band with five of us and we sang songs that he wrote. Horrible, Horrible stuff." explained Jazzy.
She also previously explained how their singing aspirations allowed them to escape their parents' grip.
"We moved out when we were 12 and 15 because we met this guy who owned a club and was looking for singers. We were, like, 'F**k, yeah!'
"But our parents believe that, once you leave, you're going to hell. We have hardly any contact with them - though our dad writes us hate mails."
Ruby added: "He thinks we're sinners and are going to go to hell for doing 'The X Factor'."
