BLACKBURN singer Nathan Grisdale is through to the infamous six-chair challenge on The X Factor.

After wowing the 5,000-strong audience in his first audition at Wembley, Nathan survived the chop as judges whittled down the contenders once more.

Former One Direction star Louis Tomlinson was revealed as mentor to the boys.

The six-chair challenge will see the boys, the girls, the groups and the over-25s further cut down from 15 acts in each category to just six.

Lancashire Telegraph:

Louis was especially enthusiastic about Nathan during his first audition saying he would love to mentor him.
