She said: "[My dad] was very proud of me. He loved this show and he was a kind man, very accepting man. There was not one bone of judgment in his body."
In a tweet shared to Ellen's account, she explained that her father's passing was expected, and she was able to say goodbye before he passed.
She wrote: "This week, at the age of 92, my father Elliott DeGeneres passed away. He lived a good long life. It wasn't unexpected. I was able to say goodbye."
She also shared touching image of a rare rainbow stretched over her show's huge poster above Warner Bros studios in Burbank.
"When I was a kid, my dad took us on one vacation to Warner Bros. Studios. He loved this business. He loved that I was in it," she explained.
"When he died, I saw this rainbow over the stage they named for me."
