Demi Lovato is reportedly dating Luke Rockhold.

And they are believed to have been sending secret messages to each other on social media, via smiley faces on their fingers.

Meanwhile, the brunette beauty recently admitted she feels "free"

since calling time on her relationship with Wilmer.

She said: "I feel really amazing. I feel really great and I'm growing.

My life is just really, really exciting for me because I'm growing.

It's new and fresh, and I feel free.

"I think I have so many people around me that I trust and that I talk to about things and they are the ones that are quick to tell me, 'Hey, you may be having a bad day but look at what you've overcome'. So that's what's really cool is to be able to surround myself with people like that."

The couple dated on and off for six years but announced in a joint statement that they had decided to call it quits.

The pair said: "After almost 6 loving and wonderful years together, we have decided to end our relationship. This was an incredibly difficult decision for both of us, but we have realized more than anything that we are better as best friends. We will always be supportive of one another. Thank you to everyone who has offered us kindness and support over the years. With only love, Wilmer & Demi (sic)."
