On Saturday's episode, viewers saw Bill's school sweetheart Sacha Cullum agree to delay their ceremony after he won a place on Danny O'Donoghue's team with his cover of Plan B's 'She Said'.
The 24-year-old has since told The Sun that they will lose money they'd put down to secure a church, reception venue and photographer for their big day.
He said: "It wasn’t an easy decision. But to be given an opportunity to do something like this is amazing. Everyone has been completely supportive of the decision. They know how much it means."
But is unclear whether Bill will make it past the Battle Rounds to the live shows, as the Daily Star yesterday reported that he has already has his stag party.
The final round of Voice blind auditions airs this Saturday at 7pm on BBC One.
