X Factor hopefuls The Cutkelvins reveal their family secrets including who has the grossest food habits

THE Cutkelvins may have wowed audiences with their polished performances on the X Factor so far but behind-the-scenes it is a different story.

In an exclusive video chat with The Sun, the siblings reveal all their family secrets, including who is the messiest and who has a really gross habit when it comes to food.

Older brothers Kyle and Jay were quick to brand younger sister Shereen as the messiest of the bunch, and also the one who hogs the bathroom.

The 20-year-old denied the accusations, saying it was actually Jay who spent the most time in front of the mirror but the boys were having none of it.

Jay said: "She leaves me and Kyle eight minutes each" while Kyle added: "And she's in there for like an hour".

The brothers couldn't stop mocking their little sister, also saying she had the most annoying habit by chewing food "as if she is chewing grass".

But the singer got her own back on her cheeky siblings when she revealed Jay's gross habit with food.

She said: "He puts tomato sauce on everything.

"He like spoils... mum cooks a nice dinner and he [puts] tomato sauce on everything."

Kyle joined his sister in revealing all about his habits, saying: "Jay puts on a wrap macaroni and cheese and tomato sauce and wraps it up.

"It's absolutely disgusting. He puts noodles in a wrap as well and puts tomato sauce on them."

Shereen added: "It's minging".

The trio - who caused a bit of controversy by not singing a George Michael song during a week dedicated to the late singer last weekend - also took aim at each other's dress sense when asked who has the worst taste in clothes.

Kyle said Jay, who recoiled and said: "Nah, I'm fly mate, look at the sight of that."
