Romestrand sent gossips into a frenzy after reportedly telling pals she stayed overnight at royal residence Clarence House, where the prince served her breakfast in bed.
A source tells Britain's News of the World, "She's confided to a few people about her friendship with Harry. She talks about staying overnight at 'the Palace'. She says he was a 'total gentleman' but doesn't divulge much else.
"She doesn't want to talk openly about Harry because she's worried it will overshadow her music."
