Julie Roberts is lending her voice to a cause that she is passionate about. The country singer, who was diagnosed with multiple sclerosis in 2005, will perform an online StageIt show to raise money for the National MS Society’s 50 Mile Walk in Charleston, South Carolina.

The 35-year-old didn't reveal she was battling the debilitating disease until 2011, but she says she was aware that there was something wrong while on the road to support her self-titled freshman record, which was released in 2004.

“It all started when I was on the road touring for my first album," she recalls. "I’d be in the middle of a show and couldn’t hold my microphone anymore. I’d have to switch the microphone between my hands, back and forth to get through a song.”

But now, thanks to a healthy diet and exercise plan, the songstress is stronger than ever. Her latest album, 'Good Wine & Bad Decisions,' was released last year on Sun Records, which she says is the most honest collection of tunes she has ever released.

“You know, I feel like I’ve grown a lot,” she admits. “But for my whole life, I always hid what my relationship was with my dad and what I grew up like. For a few years, I hid that I had MS. And now I’m at the point where, you know what, I record honest music, I record music that I can relate to. Why not?”

Roberts' StageIt show will take place on February 20 at 8:30PM CST. Tickets are available here.  All proceeds from this show benefit the National MS Society.
