Demi Lovato is happy just being herself.

The 24-year-old singer looked right at home in a stunning floral gown on the red carpet at the premiere of her new movie, Smurfs: The Lost Village, in Culver City, California, on Saturday, but told ET that sometimes she can "feel like an outsider."

"Sometimes you can feel like an outsider," Lovato told ET's Denny Directo. "I'm a homebody. I don't really like to go out and do stuff that like 'young Hollywood' typically likes to do, so sometimes I feel like I don't fit in."

"But I'm glad that I don't, I love being myself and I love who I am," she added.

Lovato voices Smurfette in the new movie, and though her character is animated, she said they have more in common than some might think.

"[I] definitely [feel like Smurfette is an extension of me]. I'd like to think we're both independent, brave and curious," she confessed. "We want to see the world and she goes out and sets on this adventure to find her identity."

Finding her own identity is something that didn't come easily to Lovato, as she told ET at the film's junket on Friday that there was a period of time that she thought she "wasn't going to work again."
