His Perfect Martini by Angel Devlin

What happens in Vegas, can’t always stay in Vegas.
Mila Williams came to Vegas to show her family that it was love not money that counted in this world. But once her allowance stopped, so did the relationship. Starting over as a cocktail waitress, Mila can’t believe the idiots who get drunk in her bar then married. She vows she’s better off alone.
Louis Clayton is an upcoming YouTube sensation, famed for his elaborate stunts and pranks. But none are more shocking than travelling to Vegas to marry a stranger, a woman he’s never met before. Louis is looking to hit one million subscribers, Mila’s just looking to forget her mundane life for one drunken night.
No one expects what happens next. Now millions know Mila’s name and Louis isn’t so sure it’s all a joke anymore.
