Iggy Azalea has threatened to sue Papa John's after a pizza boy allegedly gave out her number to his friends and family.

The 24-year-old singer is considering legal action after she received a text message from a complete stranger, who allegedly got her private details from the fast food chain's delivery guy.

Taking to her Twitter account today (09.02.15, the blonde beauty shared a screen grab of the message she was sent from the unidentified fan, which read: ''Hello is this iggy azalea my brother had delivered something from Papa John's to u and he gave me the number of Friday night i am ur number one fan call me back please is this u please answer u r my idol (sic).''

The 'Fancy' hitmaker captioned the shot, ''I ordered a cheese pizza but instead I got tons of calls and messages like this one.''

She then shared another screenshot of a conversation she'd had with the store's supervisor, who didn't seem fazed by the situation at all, and captioned it: ''PapaJohns and this is all your supervisor has to say about it #ProfessionalAsF**k (sic).''

However, the Australian stunner was left even more angered when the restaurant tried to lighten up the awkward situation by referring to her track 'Bounce' in their reply on Twitter.

The company tweeted: ''@iggyazalea #We should have known better. Customer and employee privacy is important to us. Please don't #bounce us! (sic).

But Iggy failed to see the humorous side and added: ''I don't think data breach is funny. I expect you to contact me to explain how you are going to rectify your breach of my personal information in a satisfactory and professional way or a lawsuit will be filed.''
