J Lo told reporters at the television conference that she and Marc 'have a great time working together,' but it looked like they were happy to do more than just "work together."
The former couple arrived holding hands and seemed to have their chemistry back, no bad blood in sight.
J Lo looked fabulous, of course, in a curve-hugging blue leather dress. We're sure Marc noticed how good J Lo looked as he reached out his hand to help her on stage before checking out her rings as she flashed her hand towards him.
Do they want that old thing back?
Their chemistry seemed natural, and not just for show. See for yourself in the gallery above.
