The 'Sirens' singer - who shot to fame after competing on UK TV talent series 'The X Factor' in 2010 - has hit back at her former show colleague after he labelled her difficult to work with when she appeared on the competition aged 16.
She told Digital Spy: ''It's something I find very strange, especially from an older gentleman against a young girl. ''But I'm much older and much more experienced, so it would be good to have a conversation with him now.
''To make a comment about someone you worked with two or three years ago who was 16 years old at the time, it was a little bit unnecessary. I must be on his mind. Bless.''
Luckily for Louis, 61 - who has appeared as a judge on 'The X Factor' since 2004 - Cher insists she ''never'' holds a grudge against her critics.
She explained: ''It's nice to see that people aren't getting stuck in the past. I feel the same with people I've met... that have really been quite harsh and forceful and a bit mean to me. I've seen them for the person they are now and the way they are treating me. I never hold a grudge.
''It's so much easier for me now because I feel if you're a happy and content person, there is no reason to be on the defensive.''
She said: ''Thank God for that. I will be watching this time - I can't say that I was majorly tuned in before.
''I really do feel it has been missing those judges. Their ratings will be up sky-high as soon as those two came back. The show hasn't been the same without Simon and Cheryl.''
Here are all the performances from the comeback series of 'Twin Peaks'.
He's embarking on his first ever solo arena tour.
The singer has donated half a million to relief efforts.
Pratchett died aged 66 in March 2015.
