Gwen Stefani has no doubt she'd be totally accepting of a gay son.

In a new interview with ETonline contributor Chris Azzopardi for PrideSource, the mother-of-three pledged full support should one of her sons -- Kingston, 9, Zuma, 7, and Apollo, 2 -- come out to her as LGBT one day.

"I would be blessed with a gay son," she said. "I just want my boys to be happy and healthy, and I just ask God to guide me every day to be a good mother because it is not an easy job."

For the 46-year-old, her top priority as a mother is "to be the most supportive mom that I can be."

Who knows whether she'll end up with a gay son, but regardless, it seems Stefani is already planning ahead. "I always ask my gay friends, 'OK, so what was it like when you were a little boy?,'" she said. 

During the interview, Stefani, who loves giving her kids manicures, expressed the importance of letting her kids be themselves. "As long as my boys are protected and happy and I’m spending quality time with them, whether it’s doing sports or doing nails, it really doesn’t matter," she said.

The "Misery" singer also responded to those who criticized her for allowing her sons to embrace their feminine sides.

"It doesn’t really bother me," she admitted. "As long as my boys are protected and happy and I’m spending quality time with them, whether it’s doing sports or doing nails, it really doesn’t matter."

Nor does it matter to Kelly Clarkson, another open-minded mom, who said last year, "I don't care if my kids are gay."
