Demi Lovato says she has never loved anyone as much as current boyfriend Wilmer Valderrama.

The singer has been dating the actor for a number of years and she opened up to Yahoo Beauty about her feelings.

The US star said that no-one has lit as much love in her heart as Valderrama.

Lovato said: "'I've never been more in love. I'm so excited to have him in my life as my best friend and my boyfriend."

Valderrama meanwhile recently said that he would be keen on tying the knot with Lovato.

He revealed: "She’s writing the future. I really think she’s someone... that I hope... that it [marriage] fits in our future. I mean, I’d be more than down [to marry her]. I love her so much."
