I think it's from 2011 or 2012 I just remember I used to watch the clip on mtv's hitlist. I don't know why the only words I can remember are Hollywood, and diamonds or red diamonds,and I'm not even sure that they're in the song but I can't find anything with those words. The video clip description:

There was this cute white boy on the beach like if he was waiting for someone. A pretty blonde girl meets him and they hug happily. They get on a little boat and paddled until they came to an island and got off the boat and laid down on the sand then the girl takes her shirt off wearing only her bikini and stares at the boy. Then the boy takes his clothes off except his shorts and they run into the sea. They play in the water and then they get out and the boy starts chasing the girl, and they run through the palm trees and stuff until they come across an ancient building with like a weird symbol on it, then the girl looks at her necklace and it has the same symbol.
