I do believe Selena Gomes was there when the incident took place, so to bring her in to it was fair enough. Even if any questions were inappropriate, his attitude was disgraceful.
You know, I thought for a moment that he meant 'detrimental' - because he now wants to take a very different musical approach and might feel stifled by his previous image/style. I'm still not a hundred percent sure that he didn't mean it.
He didn't mean it, as his attorney immediately repeated it but said instrumental instead of detrimental.
