Demi Lovato's boyfriend taught her to love her curves.

The 'Neon Lights' hitmaker has opened up about her anxiety and eating disorders in the past but has insisted she has learned how to appreciate her body from beau Wilmer Valderrama.

Captioning a photograph of herself posing in a skimpy outfit, she wrote: ''Learn to lurrrrrvveee yerrrrr currrrrvveees I actually used to hate them...

''But then a special someone helped me learn how to love them... And he sure loves them.... #squats #COOLFORTHESUMMER (sic)''

Meanwhile, the 22-year-old beauty previously revealed Wilmer makes her feel ''so much better'' when she has an anxiety attack.

She shared: ''The first call I make is my boyfriend. He calms me down and makes me feel so much better.

''But having people who are professionals as well and not relying on just one person is another key to maintaining a healthy recovery. I talk to my therapist. I'm actually in AA, so I reach out to my sponsor. I talk to the people around me, like the people on my team. I vocalise a lot of what I need and they're very understanding. I'm very grateful for that.''
