An Australian DJ named Ruby Rose is at the center of controversy after tweeting about a tryst she claims to have had with Demi Lovato.

The 27-year-old Rose started the rumor ball rolling when she tweeted Sunday that she was going to abstain from social media because friends of The X Factor beauty, 21, were attacking her "for being a 'scorned ex-lover' of Lovato's.

She kept the momentum at a fever pitch when she wrote on her Instagram account that she's "the one person demi has slept with that didn't sell on naked photos of her."

Rose then changed her tone somewhat as negative responses poured in, writing on Twitter, "What just happened to me on Instagram wasn't very nice and I retaliated because I stood up for myself. It's all sorted now Back to business …"

Oddly, she deleted all of the aforementioned tweets and wrote three more -- a series of vague disclaimers in which she distanced herself from the controversy and Internet smack, though not recanting the rumor she and Demi slept together.
