'Heart Attack' beauty Demi Lovato has revealed that last year's excessive rumours that suggested she was dating One Direction's Niall Horan have chipped away at their relationship to the point where they barely talk anymore.

The young superstars became friends in 2012, but their bond has apparently weakened at the hands of the gossip that followed them as when asked if they are still close, Lovato told Heat magazine "not really."

"Unfortunately, as sweet as he is, it's hard to maintain a friendship with somebody that you can't really hang out with without people automatically assuming that you're dating."

"People tweeted and either said really nice things or rude things. More nice than bad, I guess."

Writing on her official Twitter page last night (June 10), Lovato confessed that a dream of hers is to have a Barbie doll made in her likeness: "1 of my biggest dreams, having collected Barbies since I was a kid, is to have my own Barbie BUT with my actual body type.. Weight & height."
