Paula Abdul told David Letterman Thursday night on his program that she loves her job on American Idol but it is still up in the air as to whether she'll return for another season.
"I never said [I wasn't returning]. I just said that I'm not sure," Abdul said cryptically.
"It's called, um, 'negotiating'," she joked.
Drawing on his own personal experiences dealing with network suits, Letterman dryly advised Abdul to be cautious.
"One time, I tried that, I was coming up to the end of a contract, and I said, 'I don't know, maybe I won't come back,' and they said, 'Fine because we've got another guy ready to go'," cracked the 62 year-old late night host.
After taking a few good-natured swipes at her colleague nemesis Simon Cowell, Letterman turned the conversation to Abdul's relationship with her fellow co-host Kara DioGuardi.
"Kara's great," Abdul told Letterman. "I don't understand why they do this to women; they love to pit women against each other. Maybe because it's sexier, I don't know. Maybe mud wrestling, the whole thing."
