"I ain't gonna show my tail! I'm not gonna do that," the 46-year-old actress told ET. "There's some real moments where it's been a revelation to me, because I'm tough, I'm scrappy, I'm, you know, the tough one from Harlem."

Although she considers herself tough, Fields has gained the reputation of being the momma bear among her castmates.

"I don't know that I wanted to be the mother bear," the star admits. "I think that I've always been a nurturing kind of person. I'll be prepared with snacks and a towel if we're going to the lake. I think it's more just from that prepared kind of thing, or you know, voice of reasons sometimes."

"I don't know if that's my role, and in terms of fitting in, I think I'm, honestly, still finding my way," she continued. "It's not like, um, it's not like we were all alike right out of the gate, so it's... when you really think about it, it's over just a few months of time. People work on friendships for years."

While Fields is new to the cast, she says she's not former RHOA star NeNe Leakes' replacement.

"I didn't feel like there was any sense of trying to fill a void, and god in heaven knows I never looked at myself as any sort of replacement, not as a friend, not for a TV personality," she explained to ET. "NeNe Leakes is irreplaceable, so I don't think that there's any sense of, you know, trying to fill a void."

It was announced that Leakes will be returning to the reality show for a handful of episodes. To see what Porsha Williams has to say about it, watch the video below.

The Real Housewives of Atlanta airs Sundays at 8 p.m. on Bravo.
