Jennifer Lopez admits splitting with husband Marc Anthony has been ''really, really sad''.

The former couple - who have four-year-old twins Max and Emme - called time on their seven-year marriage last year but have remained friends ever since.

Now dating 24-year-old dancer Casper Smart, Jennifer admits the decision to divorce is still a painful one.

She said: ''Without going into detail ... it's just really, really sad.

''And look, we are still going through it, and it's emotional sometimes and difficult. We're still friends - and we're parents. But it's going to take time. It's tough.

''But for the most part, I feel very proud of the way we're handling it. I really do. We are doing the best we can for the kids.''

The estranged pair recently appeared side-by-side to promote their reality show 'Q'Viva! The Chosen' on 'The Ellen Degeneres Show' - a move which Jennifer says is the result of mature thinking on both parts.

She explained: ''What you saw on 'Ellen', it's very dignified and trying to be above all The Emotions and pain that come along with a divorce and a family breaking apart. This is grown-up stuff. It's real, serious, grown-up stuff.''

But on a more positive note, the 'American Idol' judge insists she couldn't be happier with her new man.

She said: ''He's adorable. But you already see that. He's a good egg. I don't want to talk about it too much. It's my private thing.''
