Rebecca Black has posted an emotional message on the ninth anniversary of her hit song Friday.

Now, in case your memory needs refreshing, Friday was an incredibly catchy song that became a phenomenon in 2011, inspiring various parodies and catapulting Black into superstardom at the age of just 13.

Sadly, despite being released by a child, the track prompted online trolls to attack Black, with some even going as far as to give her death threats, as per ABC News. Now, she's opened up about how viral fame affected her.

The 22-year-old wrote on Twitter: "9 years ago today a music video for a song called 'friday' was uploaded to the internet."

‘"Above all things, I just wish I could go back and talk to my 13 year old self who was terribly ashamed of herself and afraid of the world.

"To my 15 year old self who felt like she had no one to talk to about the depression she faced. To my 17 year old self who would go to school only to get food thrown at her and her friends."

"To my 19 year old self who had almost every producer/songwriter tell me they'd never work with me.

"Hell, to myself a few days ago who felt disgusting when she looked in the mirror! I'm trying to remind myself more and more that every day is a new opportunity to shift your reality and lift your spirit."

She continued: "You are not defined by any one choice or thing. Time heals and nothing is finite. It's a process that's never too late to begin.

"And so, here we go! This might be a weird thing to post but the honesty feels good if nothing else."

In a previous interview with the Metro, Black opened up about her hit song, saying: "At the end of the day, I was just a teenager just trying my best, trying to figure out what it all meant.

"‘I felt like people had this entire picture of who I was off of a three-minute video of a song that I didn't even write about a day of the week - really not that deep - and I just wanted to be myself."

However, while Friday might have had its dark side for Black, she said that doesn't regret releasing the single: "I've definitely learned so much and I think part of it is made me the person I am."
