The 58-year-old singer and television personality shared her thoughts Wednesday on Watch What Happens Live on how DeGeneres, 62, replaced her on American Idol following her departure from the series.
On WWHL, Abdul was asked what her reaction was to DeGeneres' casting and what she thought of DeGeneres' judging skills.
"Well, first of all, I was ready to leave, so I had already made peace with that. And I thought Ellen would be great, I really did," Abdul said.
"Her perspective was a just a fan, a regular person in the audience watching, and I thought she did a good job," she added.
On WWHL, Abdul answered other "shady" questions, including which Jackson was the best dancer.
"The best dancer? It's Michael [Jackson]," she said, referencing the late singer. "There's no one like Michael; I don't know if there will ever be anyone like Michael."
In another segment, Abdul offered her thoughts on The Real Housewives of Orange County cast. Abdul said she has "somewhat faith" in Shannon Beador's relationship with Janssen.
