Minogue is said to be feeling the tug of her biological clock, saying she wants to settle down and start a family, but she's been whining about feeling like the "odd one out" ever since Cheryl Cole joined the judges table last year.
So out with the Minogue and in with the new?
"Simon thinks Mel would be brilliant as she is outspoken, down-to-earth and won't hold back," one source told reporters.
"There were times in the current series that he felt things were a bit boring and he is certain sparks will fly with her on board… It will be interesting to see whether she and Cheryl Cole will gel or whether it will be handbags at dawn," they speculated.
How do U feel about the potential change???
