## Biography

### Backstory

When Diane was in high school, she went out with a guy named Michael Fellaryow and when she had sex with him, she used a diaphragm as her form of birth control.

Diane met Elliot Birch likely sometime in the late '80s or early '90s, and the two quickly fell in love, got married, and had three kids, Judd, Leah, and Nick. Not much is known about how she met Elliot and had her kids, aside from a story Elliot told in "The Planned Parenthood Show" but very little of his story was actually accurate. Diane and Elliot moved into a suburban house in Westchester, New York, that happened to be the last house that famous jazz musician, Duke Ellington lived in before he died.

### Current Life

Diane currently mothers her three kids and her parenting style ranges from being overbearing to psychologically abusive. She mentioned in "Cellsea" that she used to lock Leah up in a dresser drawer when she was a baby just to stop her crying and in "Obsessed", she stole Nick's phone from him and destroyed it with a fire iron in a fit on violent rage. She also occasionally insults her children, calling them names like "little fuck" and telling them to "eat shit", whenever she gets mad at them.

## Appearance

Diane has orange hair, green eyes and she is normally seen with pink eye shadow and lipstick. Along with that she wears golden earrings and a golden necklace. She wears a blue shirt that is a cross between a scoop neck and somewhat of a v-neck. Her pants are white skinny jeans.

## Personality

Diane is a loving mother and wife who can become smothering and this occasionally drives Nick Birch away. She is also afraid of her children growing up too fast as seen in I Survived Jessi's Bat Mitzvah, when she became distraught because Nick did not want to have her tuck him in, call him **Nicky** and kiss him on the lips. She can be a stern mother as seen in The Head Push, when she grounded her children, sans Nick, for having a house party while she and Elliot were out of the house.

## Relationships

### Family

* **Elliot Birch** - Diane and Elliot have a very youthful relationship, show as they once made love for twelve hours.
* **Judd Birch** - Like Leah Birch, Judd doesn't get special treatment from Diane, she grounded him too, even though he was not the one who threw the party. She grounded him rather because he was a part of it and did not tell her. Judd has not been seen interacting with Diane much either that his Gothic personality makes him hide in the shadows and not open up much.
* **Leah Birch** - While Diane loves Leah as much as she loves Nick Birch, she does not go soft on her. Diane grounded Leah when she held a house party and not much interaction has been seen between the two in the series.
* **Nick Birch** - Diane gives Nick special treatment. While she punishes Judd Birch and Leah Birch for holding a house party in The Head Push, Nick gets out without any reprimand whatsoever. However, Diane can be the mean parent when she need to. In Pillow Talk, she took Netflix away from Nick for six weeks because of him skipping school to go to New York.

### Friends

* **Barbara Glouberman** - Diane is good friends with Barbara, as their sons are best friends, themselves. In "Girls Are Horny Too", Diane gave Barbara the book, The Rock of Gibraltar to help spice up her sex life with Marty.

### Others

* **Andrew Glouberman** - Diane thinks of Andrew as family, but not much interaction has been seen between the two.
* **Jay Bilzerian** - Jay and Diane only interact in "I Survived Jessi's Bat Mitzvah" where Diane treats Jay like a son because Nick Birch drifts away from her, but Nick eventually takes his mom back.
* **Val Bilzerian** - Diane is perfectly okay with Leah dating Val, despite him being a complete perverted asshole. She does, however, have some reservations about her having sex with him so soon, as seen in "Sugarbush", but she got over that.
