The four-piece sister act, who hail from the Philippines originally, have told reporters that their mother has made them swear not to have sex or even kiss a man before marriage, despite one of them having a boyfriend.
Irene Cercado, who makes up one quarter of the group, explains to The Sun: "It is very strict in the Philippines, and so different to the UK. Our mum is very strict.
However, the girls also admit that the no-boys rule might actually help them later down the line, should they make it through to live shows, and have to share a house with the rest of the contestants.
“Some boys are good looking here, but we can’t pay attention to them. We just want to think about winning as we would love to live in London full time. If there are parties we will just drink soft drinks.”
Irene, Almira, Celina and Mylene have so far sailed their way through the competition with their imaginative and energetic routines, but their ‘X Factor’ journey hasn’t been without its controversy.
Their first audition was extremely well-received with the public, but it later emerged the group had appeared in TV talent shows the world over, and had even won some.
The band were later forced to change their name from 4th Power to 4th Impact, when a group who already had that name threatened legal action.
‘The X Factor’ continues this weekend on ITV.
