ENTERTAINMENT WEEKLY: You were selfless in your final speeches.

Big Brother: Celebrity Edition

Cliff Lipson/CBS

You didnt say anything about yourself.

I dont know what people saw at home but he played such a good game.

But you are supposed to campaign for you!I couldnt play against him.

There was two times he saved me.

I wouldnt have been able to be where I was if it werent for him.

And then I was like, Oh, I brought him!

And it was kind of hitting me while I was doing it, ohI can win.

So I just said something from my heart.

I didnt know what to say.

I didnt have a speech.

The truth was, I couldnt havenottaken him.

I wouldnt have been in the final four if not for him.

That felt like the right thing.

I know itsBig Brother.

I know its a game.

But Im also a mother.

It was the more human thing to do.

I said 10 times in the house, its not worth $250,000 to backstab or hurt my friends.

I always said I wasnt going to do that.

You didnt know Ross before this, right?No!

Its shocking, right?

People were like, You had to have known each other.

We never had a final two.

We were very honest with each other.

Truthfully, I needed to win more challenges.

I always knew you cant win unless you win challenges.

You have to get yourself to the winning circle.

I always knew I cant be taken there, I would have to get myself there.

So winning that last challenge was the one moment I really needed.

Other than that, I played the only game I could play.

I knew I had to team up with somebody who was gonna win challenges.

I got stuff with Ross, who I didnt think was gonna win a challenge.

But then he did.

It just worked out.
