Josh and Kyle Brooks are 15-year-old twin brothers living with their nan in a seaside town in Cardiff.
The boys, who also have a younger brother, used to perform separately, but six months ago their cousin suggested they perform together and it was clearly the right move!
The Brooks secured four yeses in the room and arena auditions and sailed through to the bootcamp stage to land a coveted place at Judges' Houses.
"Because we're twins we have a strong connection," said Josh and Kyle. "We've sung to each other before we could talk and find it really easy to harmonise.
"We got together about six months ago. Loads of people used to tell us that it was a good idea, as we're twins and it was very different. They said people would love it."
Being just 15, Josh and Kyle have developed strong bonds with some of the other groups. "We've met some brilliant people and built some incredible friendships with everyone," they said. "We look up to Concept like they're big brothers. They give us some great advice."
Josh and Kyle have to impress judge Louis Walsh for the all important Judges' Houses, which took place in Bermuda.
"Bermuda is amazing," they added. "It was our first time away, the first time we had ever been on a plane. It was the ultimate experience and it has made us realise how lucky we are."
