Songstress Camila Cabello, of Fifth Harmony fame, has revealed that she can't believe how much success she has enjoyed since uploading a video to YouTube of herself covering Demi Lovato's 'Skyscraper' three years ago. 

Since then, the band has toured in support of Lovato on her 'Neon Lights' jaunt, they just broke the record for having the biggest crowd at a Today Show 'summer series' concert, and earlier this year they won 2 Radio Disney Music Awards. 

Writing on Twitter about how much her life has changed in just 36 months, Cabello explained that it's overwhelming and amazing: "I uploaded my skyscraper cover of Demi lovato on YouYube 3 years ago. A meshugunna of serendipitous series of events and HERE WE ARE FOLKS. No, meshugunna isn't a word but I like to think if people long ago made up all these words why can't I do it when I feel like it."

Earlier this week, Fifth Harmony's Lauren Jauregui praised Lovato for being a fantastic role model and said: "She just stands up for everything she believes in, wholeheartedly."
