Jennifer Lopez and Marc Anthony are back together, at least for one evening.

The exes shared an emotional reunion last night in Las Vegas as they took the stage together for their ¡Q’Viva! The Chosen show at the Mandalay Bay resort.

Wearing a form-fitting sequined mini dress, Lopez walked on stage hand-in-hand with her estranged husband.
