The actress, 45, has played working mom Tami Taylor on Friday Night Lights, the haunted and troubled Vivien on American Horror Story, and now, she'll portray fading country star Rayna James on the upcoming Nashville.
But for all her characters' differences, Britton is keen on bringing one unifying characteristic to each of the roles.
"It's important in whatever character I play that I show as many different levels of what it is to be a woman as I can. That includes being sexy!" Britton tells Redbook in its November issue.
"I want to get rid of the whole idea that women who are wives and mothers and working in the world no longer have any interest in their sexuality, because that’s not my experience."
As for her experience with adoption (she brought home her son from Ethiopia in 2011) and sharing advice with other Hollywood moms who adopt, "met and Angelina and Sandra Bullock and Mary-Louise Parker just get together every weekend, drink rosé and talk about kids! No, that is not the case," jokes Britton.
"Not that I wouldn’t love to get together with all of them and discuss their experiences," she adds. "But there is a community of people who have adopted children from Ethiopia, and that's something I want to be a part of for sure. To me it's really important for my son to have a strong sense of that background."
Britton says she's also got a strong sense of herself as a single mother – even if that's not the way she'd planned it.
"I always knew I wanted a child, and I always assumed I'd be doing it with a man … Then my parents passed away within three years of each other," says the actress.
"Right after that, a light bulb went off in my head and I thought, 'What am I waiting for?' I wasn’t in a relationship at the time, but I thought, 'This is something I want to do. I can do it.' "
