It's Friday, Friday — and Rebecca Black has a new song to celebrate. The viral music sensation is back with “Heart Full Of Scars," a pop song we guarantee you won't be able to get out of your head all weekend long.

The first single from her upcoming EP, RE / BL, Rebecca, has definitely come a long way from the 13-year-old YouTuber we met in 2011. With lyrics like, "Learn to say f–k it, take my time,” and "Life’s a b—h, but I’ll make it mine,” it's a big jump from her hit song "Friday." Listen below!

And if you want to see more of the brunette beauty, who also dabbles in makeup tutorials, you can catch her, along with fellow YouTubers, on the Love is Love Tour. Joined by Miles McKenna and Shannon Beveridge, Rebecca will be singing her heart out when it kicks off in Chicago on Oct. 1.

Earlier this year, Rebecca released her first song post-"Friday" titled "The Great Divide" and it quickly jumped into the Top 25 of Billboard's Dance Club Songs chart. However, she did admit to struggling with fame at such a young age. "I'd be lying if I said I was totally over the 'Friday' stuff and that it doesn't affect me," Rebecca told Rolling Stone. "When you're 13, and you get so many people giving you death threats, telling you that you don't deserve to live this life, calling you ugly, fat, terrible, the worst person in the world, that will affect you."

She continued, "I just try to give myself a break every now and then, and take some of the pressure off of trying to prove myself to everybody." With over 1 million subscribers on Youtube, we don't see Rebecca going anywhere, anytime soon. Who's gonna get down on Friday to her new song?
