Jennifer Lopez and estranged husband Marc Anthony reunited on stage over the weekend.

The American Idol judge and the Latino singer - who announced their seven-year marriage was over last July - held hands as they appeared during the finale of the Q'Viva! The Chosen Live show at Las Vegas' Mandalay Bay Events Center on Saturday.

The event was the live ending for their TV talent program and the former couple - who have four-year-old twins, Max and Emme, together - watched the talented finalists perform.

Despite their split, Jennifer and Marc looked close throughout the night and at one point they embraced each other on stage, much to the delight of the crowd. Jennifer - who is now dating backing dancer Casper Smart - and Marc have always vowed to make their split as amicable as possible for the sake of Max and Emme.

"He's not seeking financial support from her in this divorce. This is about trying to figure out how best for two very busy parents to share their children," a source said.

However, Jennifer has admitted the break-up has been a painful process: "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."
