The 'Havana' hitmaker - who went her separate ways from the girlband in 2016 - was devastated when she saw her former bandmates appearing to knock a member of the band, thought to be a dig at her, off the top of the set when performing at the award show in August 2017.
She said: ''It definitely hurt my feelings. I wasn't expecting it, I wasn't prepared for it - especially because at that point I'd moved on from it. I was just like, 'What? Why?' ...
''I have to make space for the good stuff to happen in my life. I don't like holding onto the past, especially when it's stuff that, in my opinion, is just petty.''
The 20-year-old singer says things started to fall apart when she teamed up with Shawn Mendes for 'I Know What You Did Last Summer'.
Speaking about the experience, she added: ''I was just curious and I wanted to learn and I saw all these people around me making music, writing songs and being so free. I just wanted to do that and it did not work ... It became clear that it was not possible to do solo stuff and be in the group at the same time. If anyone wants to explore their individuality, it's not right for people to tell you no.''
Camila thinks the secret to success is just to be the ''you-est you possible''.
She told the New York Times: ''I feel like the best way to come up with something new and different is just to be the you-est you possible. If you pull from all the different little parts of yourself, nobody can replicate that.''
