Two years before Ruby Rose hit massive stardom on Orange is the New Black, she was a pretty unknown DJ … who claimed she once got intimate with Demi Lovato!

And since today is #TBT, what better way to remember it?!

Back in October 2011, the Australian beauty — who plays inmate Stella Carlin on the hit Netflix series — tweeted at the singer, "Nice to meet you today," later adding, "No idea if you got my text, my phone only works when it wants to."

Over time, Ruby, 29, got flirty with the former Disney darling, 22, complimenting her on her "inner glow" and inviting her out for coffee.

But things took a surprising turn in 2013 when Ruby wrote on Instagram, "I'm like the one person Demi has slept with that didn't sell naked photos of her." (!!!)

Naturally, Demi's fan base (they call themselves "Lovatics") lashed out at Ruby — who then cryptically wrote, "It doesn't really matter what people think. It's what you know that counts."

A source tells Life & Style that Ruby claims she and Demi dated for two years when the songstress took a break from dating Wilmer Valderrama, 35. (Demi has never addressed the claim.)

Whether it actually happened or not, both gals are in healthy and loving relationships these days. Demi is currently with Wilmer, while Ruby is engaged to 26-year-old clothing designer Phoebe Dahl.
