The Dixie Chicks have been on a hiatus since the release of their Grammy-winning album Taking the Long Way in 2006, aside from a few live dates.
Maines recently discussed the group's future on The Howard Stern Show, admitting that the public outcry over their opposition to the Iraq War a decade ago put a damper on the group's success.
"I just don't feel like it's the Dixie Chicks' time," Maines told Howard Stern. "I feel like things were tainted permanently. So, I struggle with going out on five Grammys or going out - petering out."
The Dixie Chicks were famously the subject of protests in 2003 when Maines declared at a London concert that she was ashamed that George W Bush was from Texas.
Maines went on to admit that her comments led many fans to turn their backs on The Dixie Chicks, but stressed that the group has never formally split.
"I'm still in the Dixie Chicks; we haven't broken up... I love the Dixie Chicks; it's the most fun I've ever had in my life. It was like winning the lottery," she said.
The Dixie Chicks are reuniting for two concerts this summer at the Canadian Beach Music Festival on Prince Edward Island and at the Craven Country Jamboree in Saskatchewan.
