Accidentally Famous - Marissa Clarke

Jack Winston may be Hollywood's biggest action hero, but he's seriously burned out. He can't even save himself from his PR team's latest scheme: dating a starlet. But when his assistant accidentally tags Cassidy James from Blink, Maine (wherever that is) on social media, the paparazzi decide that she's Jack's latest fling. Now Jack needs to do some serious damage control...starting with the adorable home reno pro in paint-splattered overalls.
Cassidy is not prepared when the Jack Winston shows up in her quiet little town—and whew, he is that gorgeous in person. Before she can pick her jaw up off the floor, his PR team is bombarding them with a whole new plan involving "fake girlfriend," "optics," and "sign this NDA" (whatever that is).

Now they have two weeks to convince everyone they're in a fake...
