Demi Lovato fans everywhere will be celebrating today as the Heart Attack singer marks her 24th birthday. The pop star has amassed five hit albums on the Billboard 200 chart, including the 2009 chart-topper Here We Go Again, and millions of fans following her every move. But with her honest approach to addressing mental health issues, Lovato has never been more empowering.

The Cool For The Summer hitmaker released her fifth album Confident in October 2015 and the title alone spoke for itself.

Sharing the ultimate message behind the record, Lovato told Latina: "There's a lot of pain that I experienced over the past year, and I'm so ready to write about it. I've stayed sober through it all, I'm a stronger person, but it's definitely been a very painful year."

She also stated on Twitter: "I've never been more confident in my sound. Never been so sure of who I am as an artist. Never felt this hungry and driven."

In the months since the album's release, Lovato has been driven to help others overcome their mental health issues just like she did.

The former Disney star entered a rehabilitation facility to treat "physical and emotional issues" in 2010 but she was able to battle through her depression. Lovato is now the co-founder of the Be Vocal initiative which seeks to educate others on mental health and bring the community together.

To celebrate her birthday, IBTimes UK lists Lovato's most inspirational quotes.

Demi Lovato's most inspirational quotes

"We have to figure out something as a country about how we get mental health care to be as accessible as physical health care ... if you're having conversations that are uncomfortable and you're sharing your story of being vulnerable, people relate. It's harder for people to relate to you as an artist if you only talk about your love life" – Latina.com

"I never want to be like, 'Oh, I've been through so much', like it's a sob story. I'm proud of what I've been through and gotten over and sometimes, even to this day, when I do go through something I'm like, 'OK. It's just a part of my story'. It'll be more to tell, and that's fine" – Complex

"I just think mental illness is something people need to learn more about. I want people to know it's OK to ask for help and it's okay to have a mental illness" – People

"I have never been confident enough in my own skin to feel sexy. Now that I'm feeling great and I feel confident, I'm proud of the skin that I'm in. I'm wanting to share that with the world and showing everyone how you can go from being very insecure with body image issues to feeling so proud of your body that you want to show it to the world" – promo clip for Confident album

"Get help and talk to someone. You need support, and you need someone to teach you the tools needed to get well. You can get well. I'm living proof that it gets better. It is slow and steady, but it feels amazing when you can look back over a year or two and see the progress you've made. Trust you can do it" – Web MD

"Never be ashamed of what you feel. You have the right to feel any emotion that you want, and to do what makes you happy" – Seventeen

"We all have problem areas. I'm always going to have thick thighs. I can't change that, and obsessing over it will only make me miserable. Learning to be grateful for our bodies and taking care of them are the best ways for us to empower ourselves physically, mentally and spiritually" – Fitness
