Pop singer-songwriter Iggy Azalea has a major bone to pick with Papa John's over her phone number being leaked by one of the pizza joint's employees.

Azalea took the issue up with Papa John's over Twitter. The singer received a message from a random fan, who claimed to have gotten her contact from a staff member, who delivers the goods, at the pizza establishment.

"@PapaJohns was my favorite pizza but the drivers they use give out your personal phone number to their family members," she tweeted on February 8.

The row got heated as an executive from the establishment tweeted back with a very remiss reponse, which further angered Azalea:

"@PapaJohns and this is all your supervisor has to say about it #ProfessionalAsFuck"

The pop star wanted pictures so she could identify who the delivery guy was and it seems like Papa John chose not to cooperate. She also added that it was a shame that they didn't value their customers' privacy.

This happened on the day of the 2015 Grammy Awards and Azalea had been nominated in the category of Best Rap Album for her debut record The New Classic.

Eminem won the award in that category for his latest album, Marshall Mathers LP 2.
