"Bella Traición" (English: "Beautiful Betrayal"), is the official second single from Spanish singer-songwriter Belinda for her second studio album Utopía (2006).

The English version called "End of the Day", was featured on the re-release of the album, known as Utopía², but didn't have a release, like the other two singles.

The music video begins in a library with Belinda opening a book called "Bella Traición."

She then appears in an old house playing two different characters dressed in goth costumes and singing with her band.
