Brielle Biermann Says Critics of Relationship With Mom Kim Zolciak Can 'F-ck Off' (Exclusive)

Just last month, Brielle jokingly tweeted that her mom was expecting her seventh child -- which everyone believed -- but according to Brielle, it was all in good fun.

"My mom posted a video of me on her Snapchat that really irritated me, so I was sitting downstairs with two of my best friends, and I was like, you know what, I'm gonna tweet that she's expecting," Brielle told TooFab in a recent interview. "I didn't think it would take off as quick as it did, but within 10 minutes, it was everywhere. I was dying laughing. She wasn't even mad, she was just like, 'What the f-ck is wrong with you?'"

But not everyone thinks Kim and Brielle's online banter is as comical. One of Kim's biggest critics on this season of "The Real Housewives of Atlanta" is Kenya Moore, who trashed Kim for a tweet she posted back in May, jokingly asking Chrissy Teigen who Brielle had to "blow" in order to meet John Legend at his Atlanta concert. Chrissy ended up replying with this:

But Brielle's message to people critical of her friendly relationship with her mother is simple: "F-ck off."

"It's my life, and I don't know why people are so concerned with it," she said. "I understand I'm in the public eye and people are interested, but my life does not affect you, and until it does, just let me live my life the way that I want to."

"People see my relationship with my mom as too friendly, but I don't think you could ever be too friendly with your parents," she explained. "I think some parents aren't close enough with their kids, and communication is key in my family. My whole life, I've told her everything that goes on, even stupid things or things she may not be comfortable with hearing. She is truly my best friend, and I hope that it stays that way.

"I tell her all the time, I'm like, 'I know I'm your favorite,'" Brielle said. "We're super close, and I just like to f-ck with her."

I have a very loving and understanding family in most situations. The first child is supposed to be the example and go to college and have their life figured out already, and that's just not the dynamic in my house. We're kind of just like, whatever you wanna do, go for it, we support you 110 percent. If I wanted to live at home for the next 20 years, with the way my mom is with me, she would love that.

I don't feel like there's a lot of pressure on me. I just try to be a good example for Ariana because she is 16, she has a boyfriend, she's starting to go out and be able to do more things. I was never a party-er or like boy crazy back then, so I just try to let her know she has to be careful. I just want her to have a good head on her shoulders.

People see only 30 minutes of my life once a week for like 12 weeks and that's it. They don't really know me, they don't know what goes on behind the scenes and they don't see what really happens. They feel like they know us because they see the show, but that's not who I really am. There's a certain image I want the world to see and a certain image I have for my family and friends. I feel like everybody needs that balance. I'm not this ditsy, crazy girl that has no goals in life. I'm just struggling to find my passion.

I always tell my sister my life would be so boring if I was kind of normal. I feel like Hannah Montana because some places I go, people know who I am, some places I go, people don't. I have the perfect balance. I'm always like, will I even have any followers if I wasn't in the public eye? So it's kind of cool, but it's hard to be private.
