has come out in favor of marriage equality.
"As a married person myself
, I don't know what it's like to be told I can't marry somebody I love, and want to marry," the "Jesus, Take the Wheel" singer – and devout Christian – told Britain's The Independent
"I can't imagine how that must feel," she said. "I definitely think we should all have the right to love, and love publicly, the people that we want to love."
Underwood says it's actually her faith that's led her to support gay marriage.
"Above all, God wanted us to love others," the recent CMT award winner
said. "It's not about setting rules, or [saying] 'everyone has to be like me.' "
"No, we're all different," she continued. "That's what makes us special. We have to love each other and get on with each other. It's not up to me to judge anybody."
The former American Idol
winner, who was raised Baptist, recently switched to a nondenominational congregation along with her husband Mike Fisher
, a professional ice-hockey player.
Underwood joins other stars such as Anne Hathaway
, Daniel Radcliffe
and Chris Evans in supporting marriage equality.
