Jennifer Lopez and Marc Anthony

Rumors circulate that Jennifer Lopez has hooked up with estranged hubby Marc Anthony at Puerto Rico hotel. According to sources, the twosome spent the night together while filming their talent competition Q’Viva! The Chosen in Puerto Rico on November 8th.

According to Us Weekly, Marc Anthony, 43, was spotted picking up Jennifer Lopez, 42, at the airport, and “Marc never stayed in his hotel room.” Friends believe that the parents of 3-year-old twins, Max and Emme, will share more intimate moments again when they shoot “Q’Viva!” in December.

However not all of them agree, as another pal believes an actual reconciliation is not going to happen.

“They may sleep together, but they’re over.”

Meanwhile J.Lo reportedly has hooked up with her 24-year-old dancer Casper Smart. Sources say that the two of them packed on PDA when attending an after-party for the 2011 AMAs at Greystone Manor in West Hollywood.

As for their talent show Q’Viva! The Chosen, it is scheduled to air in the US on Univision in early 2012.
