The 'Want U Back' singer accepted boyfriend Craig Monk's proposal earlier this year, which she explained has given her a more "calm" outlook on life.
"I feel like being with Craig has changed me a lot," she told MTV News.
"I feel I'm a lot more calm, I haven't got an attitude any more. I had a stinking attitude, it was awful."
She added: "I have learned to appreciate things a lot more now I'm with him."
Lloyd said back in April that she wanted to get married to Monk "as soon as possible".
The former X Factor contestant broke the US iTunes top ten chart last week with 'Want U Back'.
