Her family is of Russian Jewish descent and her real name is Katherine V. Litwack. When she decided to become an actor, she changed her name to a stage name that would roll off the tongue a bit. She hoped that the name Kat Dennings would make her more marketable.
Glasses can be hard to pull off for some, but Kat can certainly rock a pair of glasses. And Kat is near-sighted in real life so they aren't just for show. You will usually see her in contacts when she is working and in glasses in her real life.
Way before 2 Broke Girls, Dennings got her first big break in Sex and the City. She played a spoiled Jewish girl that was gearing up for her Bat Mitzvah. Throughout the whole episode, she did her best to torture Samantha who was the one who had to plan the party.
Here is a fun fact! Kat played Bob Saget's oldest daughter in the show Raising Dad in 2001. Mary-Kate and Ashley Olsen played his youngest daughter in the show Full House. Kat was born on June 13, 1986, the same day and same year as Mary-Kate and Ashley Olsen.
She knew that she wanted to be an actress at a very young age and her family wound up moving to Los Angeles so she could have an acting career. Because of this, she was home-schooled for most of her life and wound up graduating at only 14 years old. What a smarty pants!
Her and her brother Geoffrey wrote a screenplay together called Your Dreams Suck. It was so good that it wound up on the 2008 Black List of Best Unproduced Screenplays. The Black List is a list of the best unproduced screenplays that agents receive every year. Many of these works go on to become features.
At one point, she went Pinterest crazy and tried dying her hair with coffee. She talked about it on her Instagram page with the caption, “tried dyeing my hair with coffee today. I used conditioner and 6 packs of instant Starbucks. The results are barely noticeable but now I smell like ITALIAN ROASTTTTT.”
Kat collects old books and is a major book nerd. She recently told Ellen in an interview that she is in a book club with Beth Behrs and a group of their friends. The name of the book club is "Grape Expectations."
This may come as a surprise, but her acting icon is none other than Christopher Walken. She looks up to Christopher Walken and even credits him for inspiring her to become an actor. And perhaps inspired her to need more cowbell?
Some jerk hacked into her phone and leaked topless pictures of her in 2010. Two years later, they resurfaced and she paid them no mind and the news went away on it’s own. She handled it like a champ, but people can really suck.
Like many celebrities, Kat practices Transcendental Meditation. This is an effective way to separate anxiety and stress from your body and it is a huge hollywood trend. Actors like Oprah, Hugh Jackman, Katy Perry and Jerry Seinfeld all use it as a tool to keep calm and carry on.
Denning blogged on her website,katdennings.com for almost ten years. She also did some vlogging on Youtube before she hit it big. Check out her archives to see what the younger Kat Dennings was up to before she was a star.
In the beginning of her career, she did a ton of low-budget indie flicks. She accepted her role on 2 Broke Girls to switch things up a bit.
“I think it got to a point where I have done so many small films, and I’ve worked really, really hard, and these things sometimes they just disappear. Four months of your life never gets seen, and you start to feel kind of tired.”
Kat is an East Coaster at heart. In an interview from 2008, she talks about how she feels about living in LA.
"S**t is crazy out here. I tried being anorexic for four hours, and then I was like, I need some bagels. I'll never feel comfortable in L.A., really. I knew these nice girls that lived in the Valley. I had no idea they were on meth."
