The 'Crazy Stupid Love' singer wed her French beau Jean-Bernard Fernandez-Versini in a private ceremony on the Caribbean island of Mustique earlier this month and Cher - who married long-term boyfriend Craig Monk last year - believes thinks it's ''amazing'' her former 'X Factor' mentor has found love again.
Speaking on Birmingham's Free Radio, Cher said: ''I'm really happy for her. There is no reason for anyone not to be happy for her. I have been looking at Twitter a lot and a lot of people are saying, 'Oh, three months this and three months that.'
''You can't put a time on anything and people should realise you only have one life and you don't know what is going to happen to you.
''So I feel that it's amazing for her to be able to do that, and fingers crossed she has little babies. She is going to have beautiful children.''
The 20-year-old singer also offered Cheryl, 31, marital advice, cautioning the singer to ''pick her battles'' with Jean-Bernard.
She said: ''One of the things I have learned is pick your battles. If he's left a wet towel on the bed, pick it up and remove it yourself. There is no point going over the same thing again and again, because he won't listen. He will not remember to not put a wet towel on the bed.
''But then in other situations where he's really hacked you off, that's your battle that you pick. That's something that I do.''
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.
