Have the recent divorcees rekindled the flame?

E! News reported last Tuesday that Jennifer Lopez and Marc Anthony were spotted together in Puerto Rico on a business trip.

Anthony's rep, Bianca Lasalle, told the network that the former couple was on the island filming auditions for their new talent show, Q'Viva! The Chosen.

But could Lasalle be a little out of the loop in her client's life?

On Monday, Us Weekly reported it was less work and more play after hours.

A source told the magazine, "Marc never stayed in his hotel room."

And amid rumors Lopez has moved on with backup dancer Casper Smart, her friend doesn't believe the 42-year-old singer and actress is completely over her ex.

"[A hookup is] inevitable," the friend said. "Marc has this hold over her."

The friend added Lopez has been on an "emotional roller coaster" since ending her seven-year marriage.

However, another friend insisted that at the end of the day the two are just business partners saying, "They may sleep together, but they're over!"

Lopez and Anthony have two children together, 3-year-old twins Max and Emme, and at Sunday's American Music Awards, they also shared custody of Pitbull.
