Selena Gomez new movie

In my dream I was watching a Selena Gomez movie, it was a rom-com where she worked at the City hall and her boss had a crush on her but he was a player and was a total flirt. Her characters name was Mariana Barba and she was some sort of assistant, but not his. In the movie he was constantly buying her nice things cuz he was rich and flirting a lot. The actor who played David aka the boss was Austin Stowell. When i was watching i thought the movie itself was stupid cuz he was such an asshole since he had a super model gf but would still flirt with Mariana and try to be with her and she was just nice and kind, didn't lead him on a lot, even though she knew she had a gf.
