Daily Mail are reporting that New South Wales police confirmed they received a report and are currently investigating the accusation so "no further information is able to be provided".
Jen reportedly told police that Blake, who was recently eliminated by Sophie Monk from the Bachelorette, threatened to sell nude photos she had sent to him during their relationship.
Daily Mail have reported that Blake has received an apprehended violence order and can not enter NSW, Jen's home state.
More to come.
