Australian woman Jessica, 29, has opened up on the break-up prank from her former lover, who has offered $100 for the best impression of the 'Star Wars' character to try and encourage people to call her up.

She told 9News: ''I'm getting phone calls at really strange hours of the night, about one o'clock to about four o'clock, aye.

''I thought it was quite funny actually, I thought it was a good joke.''

She claims she ended the relationship after catching him allegedly cheating on her.

She added to the Cairns Post: ''Just pull [the posters] down please and yeah, have a laugh for me and if you want to make a phone call, go for it. I don't mind, bring it on!''
