Singer Miley Cyrus opened up to an Australian media outlet about her life and the fact that Googling yourself hurts your brain.

She admitted posting photos of herself smoking pot on Instagram because she was brought up believing that weed isn't a bad thing. Although she deems smoking marijuana as normal, she shared that she doesn't promote the drug in her songs. "It's not like I'm sitting around telling a bunch of kids to do a bunch of drugs," she shared.

The 21-year old singer, who has a tattoo saying "love your brain", shared what is truly detrimental and what really hurts her brain. She answered, "Googling yourself."

She goes on to explain that Instagram and Facebook comments, hurt her brain.

"I have a 14-year-old sister and I go through her comments and people are calling her a slut, and that's a 14-year-old. So I think that's hurting your brain," she added.

Miley Cyrus' younger sister Noah is a former child star known for her voice work on the animated movie "Ponyo". Noah also guest starred in six episodes of Miley's now-defunct series, "Hannah Montana". She is often criticized for trying to mimic her older sister's wild ways.

Cyrus also addressed brain-hurting comments about her infamous 2013 MTV Video Music Awards performance with Robin Thicke.

The singer shared that no one talked about how Thicke performed. All eyes and all blame were on her. Cyrus shared that she found it funny because she didn't really think about the implications of the show. "Literally, I never thought,'Oh this is like a married dude that I'm dancing with this way'," she explained.

Despite the name-calling and the brain-hurting comments from the performance, Cyrus came back to the VMAs this year and won the Best Video award for 2014 for her smash hit, "Wrecking Ball".

However, she took a backseat as her homeless friend, Jesse, received her award for her as she teared up watching.
