The 24-year-old singer, who is engaged to Rixton's Jake Roche, says she was shocked to be sent a barrage of abuse on social media but is trying to rise above it, reported Cosmopolitan magazine.
"It used to make me cry. I was shocked at the time. I was a young girl and I thought, 'What have I done to you? Why do you have to be mean to me?' I'm not a nasty person and I took it to heart. Some of the things people said were disgusting. It really affected me."
"To be honest, we're just loving what we're doing and we get to experience all of this together, which is amazing. There aren't many people who can say they see different things every day.
"We genuinely get on so well, and even though we're in each other's pockets, we never argue - and no one believes us, but even when we get done with work for the day, we still want to have sleepovers. It's like we're addicted to each other.
