Is Demi Lovato is bisexual?! Adorable Australian DJ Ruby Rose shocked fans on Sunday when she announced via Twitter that she had slept with the "Heart Attack" singer in the past.

On Sunday, the DJ from down unda sparked some major media attention when she wrote a mysterious tweet: 'Think i'll take a few days off social media while @ddlovato's friend attack me for being a 'scorned ex-lover.'"

The 27-year-old Aussie also added fuel to the girl-on-girl fire when she claimed on Instagram that she was, "the one person demi has slept with that didn't sell naked photos of her."

Hmm Ruby, not sure if you should brag about how great it isn't that you haven't sold photos of Demi when you (possibly) outed her via social media!

Given that the X Factor judge is pretty much an open book, talking candidly about her addictions, past relationships and boyfriends, we'd be pretty surprised if this were true. But ya never know, girls just wanna have fun!

Ruby has subsequently deleted the eyebrow-raising posts from her account after getting exorbitant attention from Demi's die-hard fans.

'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," Ruby wrote. "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 has yet to comment on the alleged tryst.
