Demi Lovato is open to dating a woman.

The 25-year-old singer - who was previously in a long-term relationship with Wilmer Valderrama - is ''very fluid'' and happy to ''flirt'' with both males and females.

She said: ''I'm very fluid, and I think love is love. You can find it in any gender. I like the freedom of being able to flirt with whoever I want.''

And if she does meet someone she likes the 'Confident' singer isn't afraid to make the first move.

She said: ''I'm normally the first one to make the move. I'm always the one who says, 'Let me get your number.' Or I slide into their DMs on Instagram.''

Though she's been single for almost two years, Demi insists she isn't ''suffering''.

She told the new issue of InStyle magazine: ''I'm not suffering because I'm alone. There were many years I was in a relationship and I wasn't learning about myself. Now I'm learning about what I like, what I need, and what I want.''

The former 'X Factor' judge has been open about her battles with addiction, self harm and eating disorders and she hopes to be the kind of role model for young people that she herself didn't have when she was growing up.

She said: ''I grew up in the era of really, really skinny celebrities. That was the look. And it was cool to be seen partying. Drugs were glamorised, and when I was 12 or 13, nobody [I looked up to] was talking about mental illness. Nobody was talking about eating disorders. Nobody was talking about cutting. I wanted somebody for my little sister to look up to. I took on that role because I knew it was important.''
