J-Lo And Marc…Did They Hook Up?

According to a source, Jennifer Lopez and ex-husband Marc Anthony hooked up Nov. 8 in Puerto Rico while shooting their talent competition show  "Q'Viva! The Chosen."

The source told Us Weekly that Anthony was seen picking Lopez up at the airport, adding, "Marc never stayed in his hotel room." And friends say it'll happen again!

The couple, who've been divorced since July, will resume shooting "Q'Viva!" in December.
