Did Demi Lovato have a lesbian fling with an Australian DJ?  That's what Ruby Rose is claiming on Twitter!
Demi Lovato is known for her open and accepting stance towards lesbians, gays and bisexuals, and she has advocated for gay marriage.  She rose to fame as a Disney Channel star, and since then has been a judge on the X Factor.  Currently she is playing a role on Glee, and she shares a bisexual kiss with Naya Rivera - recently engaged to Big Sean - on the second episode of the new season.  Naya Rivera says "It tasted like talent".  Demi sure is a talented singer!
An Australian DJ, Ruby Rose, said on Instagram that she was "'the one person demi has slept with that didn't sell naked photos of her"
She followed up with: "Think i'll take a few days off social media while @ddlovato's friend attack me for being a 'scorned ex-lover'"
Ruby has deleted the messages referencing the lesbian fling with Demi Lovato from her Twitter account, saying: "'Listen, im in no way shocked or offended by the shade im getting from people who have simply cropped my reply to what actually started this"
"However I in no way initiated this, nor did I say something that wasnt already written in the ridiculous post. One sided replies dont cut it. However, love and peace to everyone. It is what is it."
Demi Lovato's representatives have so far not responded to requests for comment on the possible lesbian relationship.
We know that Demi Lovato has had straight relationships before - she dated Wilmer Valderamma, Lindsay Lohan's notorious ex.
