Jennifer Lopez on Katie Holmes and Tom Cruise's divorce: No one wins - everybody's heartbroken
J-Lo, 42, says TomKat's shock break-up has brought back memories of her own split from third husband Marc Anthony, 43, last year.
'I heard about it when I was in South America and I was stunned,' reveals Jennifer.
'I'm sad for them. They're both really lovely people. And just like Marc and I, it's not what you want to happen. You fight and you try until you realise you can't any more.'
Jennifer hopes that Tom, 50, and Katie, 33, can keep things amicable for the sake of daughter Suri, 6, and his adopted kids Isabella, 19, and Connor, 17.
'I just wish them peace in their decision,' she tells Entertainment Tonight.
'[Especially] for Suri and their other children as well, because you become such a family. It's not just Suri - it's Connor and Isabella and everybody.
'And when that breaks apart, nobody wins - everybody's heartbroken in some way. I just wish them peace.'
Jennifer, who admits she's considering quitting her role as a judge on American Idol, is now dating toyboy Casper Smart.
