The Mirror report that the show has decided not to show the audition of Jack's dance group, who have since decided to withdraw from the competition.
Jack, 25, was part of a five-man troupe, Green Force Five, that made it through to the semi-finals of the new series but before the show aired Jack's family confirmed he died on March 17.
She told The Mirror: 'We don't know why he did it, he didn't leave a note. He did not have depression.
'Suicide can happen to anyone at any time. People can't believe Jack is gone. We are the same.
'I want people to know that this can happen to any family. There is no stereotype – it doesn't have to be a manic depressive who has shown signs of mental health problems.'
