Sexy Stamp: Ariana Grande
She explained: "I stick to the truth. I know my truth. I pay attention to the positive.
"For a while I was very upset by it, the negativity, but then I realised it's not my business what others think of me. It's my business to stay grounded and focused and not get derailed by any negativity.
"I've completely detached myself from it. I know what's real. Those that don't understand me, don't need to."
The 21-year-old performer - who sang her hits 'Problem' and 'Break Free' at the awards ceremony - confirmed however, that the diva accusations are false, saying she's just eager to succeed.
She continued: "There's a big difference between being determined and being a bitch. A lot of people don't understand that."
"There are a lot of unfair assumptions that everyone is making."
The star - who is dating rapper Big Sean - added that although she is not a diva, she refuses to be bossed around and has a clear vision of how she sees her career progressing.
She told The Sun newspaper: "I would rather have a strong vision and be in control than be a manufactured pop star that dresses in a certain way because they're told to and makes changes because they're told to.
"I'm going to make changes and evolve because I'm ready to."
