Demi Lovato feels "free" following her split from Wilmer Valderrama. The former couple called time on their relationship last month after nearly six years together, and while it was a tough decision, the raven-haired beauty admits she is "excited" about what lies ahead in her life. 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 23-year-old star insists she will not hesitate to change something about her life she isn't enjoying, but hasn't cared about what her haters think she was five years old. Speaking on 'Elvis Duran and The Morning Show', she added: "I stopped giving an 'f' at like 15! Actually like five. "You only get one life, so if you don't do what makes you happy in this moment, you're doing yourself an injustice for the rest of your life. "If you find yourself in a situation where you think maybe I'm not happy right now, maybe you have to make changes." Demi and Wilmer vowed to remain friends following their split. Announcing they were going their separate ways in a joint statement last month, the pair said: "It read: "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)."
