Despite their disagreements, Cowell and Minogue did occasionally find common ground and were able to work together effectively at times. However, their relationship was never truly harmonious, and it ultimately came to an end when Minogue left the show in 2010.
In subsequent interviews, both Cowell and Minogue have spoken about their time on The X Factor and their relationship with each other. Cowell has expressed regret for some of his comments towards Minogue, and Minogue has said that she ultimately decided to leave the show because she felt she was no longer being treated with respect.
Overall, it seems fair to say that Cowell and Minogue did not have a particularly positive relationship during their time on The X Factor. However, it is also worth noting that they were both successful and respected figures in the music industry, and their disagreements did not prevent them from making a significant impact on the show.
