For the past few days, the girls have been non-stop flirting online.
Demi was commenting on Ruby's hot photos during 4th of July, with LOVE HEART EYE EMOJIS!
Ruby simply replied with "@ddlovato hurry!"
It didn't even stop there.
Ruby later posted a leg selfie of herself chilling on a boat, and she TAGGED DEMI ON HER VAG!
Since then, they've been continuously flirting back and forth online.
Now things between Demi and Ruby aren't completely random. Back in 2013, claims came out that the pair actually dated for two WHOLE YEARS!
Apparently, the pair were a thing during one of Demi's breaks from then long-term boyfriend Wilmer Valderrama. At the time, Ruby took to Instagram writing, "I'm like the one person Demi has slept with that didn't sell naked photos of her."
Demi also responded to a rumour about her and Ruby with Complex, saying, "I did not have a relationship with Ruby Rose."
Her extended response read:
"I don’t feel like any of my past or future — when it comes to relationships that may have happened or not have happened — are of any concern to anybody. What matters to me is my relationship with Wilmer. We are in an amazing place. Rumours are rumours, and people are going to spread them. You can believe what you want, but no, I was not in a relationship with her."
"By the way, love is fluid. Whether there’s been rumors with one specific person or not, that’s all that matters. Humans are humans, and when you connect with somebody on a spiritual level it doesn’t matter. I don’t want people to ever look at the past or rumors or anything and try to figure me out. There’s a lot of relationships that I’ve had where nobody has even guessed it. Not everybody knows everything about me. The only thing that matters to me is that people know who I am today. With Wilmer, I’m the happiest that I’ve ever been, so that’s all that matters to me."
But who knows what will happen now!
