While they look very much in lockstep with one another, the reunion of Jennifer Lopez and her estranged husband Marc Anthony is all business.

"Jennifer and Marc were filming their show Q'Viva! The Chosen together for the first time in Puerto Rico last Tuesday," a source tells PEOPLE. "They were there to audition talent."

Lopez, 42, and Anthony, 43 announced their split in July, but have said they intended to maintain a working relationship for their new talent show.

In The Chosen, from American Idol creator Simon Fuller, Lopez, Anthony and tour-director-to-the-stars Jamie King will travel to 21 countries across the Americas. They will be searching for the "world's most extraordinary talent," Anthony has said.

The show is set to air in the United States in early 2012.

Lopez appears to have moved on romantically, and has been linked with dancer Casper Smart.
