Demi Lovato split from Wilmer Valderrama because she wanted a "fresh start".
The Cool For The Summer hitmaker ended her relationship with the 36-year-old actor earlier this year and whilst she initially found it "hard to depart" from him, she feels it was for the best.
She said: "I think it's healthy to be able to start over with someone else. Being sick was always a part of my relationship with him; I always had something wrong with me. I needed to let go of that.
"It was hard to depart from somebody who saw everything, but it may be nice to start fresh with somebody. Because that person I was when I was a lot younger is not who I am today."
And the 24-year-old singer has been looking to her close pal Nick Jonas to act as her wingman now she is single.
She added to the November issue of Glamour magazine: "We're definitely each other's wingman/woman. There was one night in New York where he introduced me to somebody. And Nick and I looked at each other and high-fived each other."
Meanwhile, Demi previously admitted people "looked at her differently" when she returned from rehab.
She said: "I think people looked at me differently. I wanted to prove to people that I wasn't just a stereotypical Hollywood starlet who goes to rehab and falls back into the trap of the things that got her there. I wanted to make sure that the music that I made was great and that I was passionate about the music that I put out and I sang my heart out.
"And I also wanted to continue the message of using my platform for more things than just singing about heartbreak. That's what music is for, is getting you through times, but also using it to inspire people."
