Williams originally joined the show in Season 5 and held a peach nine seasons before stepping back.

But when I did theUltimate Girls Trip, I have to say, I got the bug back.

And [after that], conversations started to be had, and it just ended up working out.

It was like Big Sis, Little Sis, and I looked forward to that.

However, the two were able to come together and form a bond and friendship.

I basically let bygones be bygones.

So we decided to really start from a brand new place.

I was looking [into] the camera.

We had to get used to having the cameras around us.

I have a new movie coming out [Pilar] saw the premiere.

Shes like, Mommy, whens your movie coming out?

On being part of the Lifetime movie, Williams said, Im a big fan of the series.

First of all, love, love, love, all those women.

The storyline has just gotten better and better and better.

I think its going to be one of the best installments of [the franchise].

It will be the last [but] I think it will be the best.

She is a detective.

So I think its going to be really good.

She was so delayed and trying to have a shock moment with that.

I mean, Ive been trending for three years.

Shes got to learn.

Her shade was very dry.

She continued, You got to speed up the process for some people.

I dont want to let them drown.

Williams told us about what she enjoyed most about returning toRHOA,it was her reunion with Phaedra Parks.

I enjoy the reunion of Frick and Frack.

Shes doing everything, and were both very busy, she said.

I think that was probably one of the highlights.

Cynthia is another highlight.

Shes like some of the younger girls are calling her auntie.

And shes a good Kiki!
