Lovato has just resumed her Neon Lights World Tour and is traveling across the U.S. She stopped for a moment to gives Radio.com a quick update on how it's going and what she's up to.

How do you keep the tour fresh for yourself and your fans? Every night is different because I'm in a new city and performing in front of a new crowd. Compared to my Neon Lights Tour, which wrapped earlier this year, fans can expect a few more surprises during my World Tour as well as special guests Christina Perri, MKTO and Becky G.

I've been fortunate enough to have an amazing crowd at every show. The energy definitely affects my performances in a positive way - there's no better feeling than performing in front of an audience and seeing my fans singing my songs with me.

What are your top three favorite Demi Lovato songs? Do they change depending on whether you are performing currently? They do change. Right now I am enjoying "Really Don't Care" because it's such a fun song to perform. I also love "Nightingale" and "Neon Lights."

What is going through your head as you perform? For me, it's about connecting with my audience, focusing on the music and putting on a great show for my fans.
