The Lee Daniels' The Butler star threw her support behind Barack Obama, who became the first African-American president in 2008, and now she is hoping to see a woman make history in the White House.

"I'm with her, I have to say I'm with her, and I would also say that regardless of your politics you cannot be a woman in the world and not see that this is a monumental time for women breaking the ceiling," Oprah told U.S. breakfast show Good Morning America on Thursday (16Jun16).

The 62-year-old is known for breaking many glass ceilings in her life and career, but she admits she is now more content living the way she wants to and only taking on projects she chooses - like her new TV series Greenleaf.

"Sometimes I'm speaking somewhere and somebody will do a resume and they'll talk about all the stuff I've done and I often think nobody ever says, 'Wow, she is so content, she has so much peace, she has so much happiness'," she said. "So I'm at a point in my life where I'm actually... for years in my magazine I've talked about balance and living your best life, I'm actually am doing it. I actually really only do what I want to do, when I want to do it."

She is also gearing up to launch her own imprint with a book titled Food, Health and Happiness: 'On Point' Recipes for Great Meals and a Better Life, which will hit stores next year (17).
