Singer Demi Lovato praised an unlikely person for her contributions to the improvements to society: Kim Kardashian.

She was not the only one the 22-year-old singer praised; she included Beyonce and Jennifer Lopez among them too. She thanked them for changing the way women look at themselves.

In an interview with Access Hollywood, the former Disney star talked about how women like them had changed perceptions of beauty away from the skinny girl type of look and allowed girls and women to embrace their curves.

"When I was growing up and when I was a pre-teen, the people that I had to look up to [for] body image [were] extremely underweight... [They] were all very bony at that time and that was the in thing," she said, but Lovato is glad times are changing.

"I really credit women like Beyonce and Kim Kardashian ... [they] completely revolutionized what our generation's view of perception of what beautiful is and I really think that they had a huge impact on that. You can think whatever you want about the Kardashians, but they really did help tons of women feel comfortable in their own skin and I like to carry that message on."

Lovato had struggled with appearance and weight issues since her time on Disney. According to the Los Angeles Times, Lovato met Kardashian in 2010 at the White House Correspondents Association dinner. Soon after she checked herself into rehab for various problems, including bulimia.

When asked about why she posted a photo collage of previous VMA appearances, Demi reflected on her look then compared to now.

"The very first time that I ever went to the VMAS and I just looked so bony and fragile and unhappy. Yes, I was at the VMAs and I was 16 and I was having an incredible time, but at the same time I was miserable," she told Access Hollywood.

"I look back at that and I think you know what, I may have been thinner, but I am so happy that I am healthy today and I have curves which are a lot more sexier than what I was aiming for. I think curves are beautiful and I feel great."
