According to a 2018 Wall Street Journal article, Perry, 34, makes $25 million each year for acting as a judge on "American Idol," which now airs on ABC after 15 years on Fox.
Abdul, 57, who served as a judge from 2002 to 2009, is rumored to have earned between $5 million and $8 million per season.
On an episode of "Watch What Happens Live With Andy Cohen," a caller asked Abdul about her thoughts on Perry's salary.
"Well, good for her, good for her," said the "Cold Hearted Snake" songstress. "Why not?"
Cohen, 51, praised Abdul for not being bitter about the pay difference.
Abdul expressed similar thoughts in a 2017 interview with "Entertainment Tonight," adding: "Let's just put it on the record, I was not getting paid $25 million."
In 2017, on "Cubby and Carolina in the Morning Show," Perry discussed her excitement over her salary.
"I'm really proud that, as a woman, I got paid," Perry said on the show. "I got paid more than pretty much any guy that's been on that show. And by the way, I love men."
As far as the rest of the judges, Richie, 70, earns $10 million, host Ryan Seacrest and Bryan, 43, each earn $12 million.
