The singer has sold her house in London and bought a property in Hollywood. The 26-year-old said she is moving to Los Angeles because her talents are appreciated more in the US.
"In America they see me as a singer, whereas here I feel that people don't appreciate my voice. I've dedicated my life to singing and I want it to be taken seriously. Here it seems all people want to know is what I've had for breakfast and who I'm sleeping with," she told a Sunday newspaper.
The former coach on BBC show The Voice came out as bisexual in 2011. She admitted the problems could be of her own making, adding: "I should just say nothing."
