Steal My Girl (Harry Styles and Pauly D fan Fic)

Two years ago 19 year old Mia Ava Terroli moved to Vegas from Los Angeles. She wasn't having any luck as an aspiring singer in LA so she took her talents to Las Vegas where she met a famous reality star DJ Pauly D. They instantly hit off and she quickly turns a player into a one woman man. Until it is leaked he father a a child with another women. They break up which causes Mia Ava to write a song that will turn into a huge celebrity. She then meets Harry and he mends he broken heart. What happens when Mia Ava and One Direction join forces and go on a mega tour together? And DJ Pauly D is the opening act? Will Mia Ava and Harry be together forever? Or did Mia Ava never get over pauly D? ( yes I know it's a weird team up but it may work. Btw I will use famous songs as Mia Ava, but keep in mind that this is fan fiction so everything goes.)
