Saved by the Movie Star by Michelle Pennington

She’ll risk anything for the role of her dreams—anything but her heart
Veronica Pantoni is a rising star in Hollywood, but her last movie came with unexpected consequences. When the movie’s A-list stars and real-life couple, Chris Sanderson and Kim Donnelly broke up, rumors that it was her fault went viral. It wasn’t fair. Despite her growing attraction to him, they’d been nothing but friends and professionals. No one will believe them, however, so the only thing she can do is wait for the scandal to be forgotten. When she’s offered a chance at her dream role, she can’t believe her good fortune—until she learns that Chris Sanderson will be her costar and love interest. Not only will it continue to fuel the rumors that haunt her life, she’s not sure her heart can handle being so close to him again. Still, she just can’t turn it down.
Chris Sanderson knew the fallout from his break up with Kim would be rough, but he had no idea Veronica’s name would get tangled up in the inevitable rumors. Maybe if they hadn’t become such good friends and had such great chemistry, the rumors never would have started. But as bad as he feels, he’s determined to make another movie with her because she brings out the best in him as an actor. He’s tired of being seen as nothing but screen-candy and knows that she is his best chance at earning real respect as an actor. The only hard part will be remembering his oath to never get involved with a costar again. Especially when their chemistry begins to flame into something more.
But it isn’t long before they discover that love isn’t the biggest danger they’ll have to face.
