Jennifer Lopez divided time between her current and past loves, Casper Smart and Marc Anthony, in Puerto Rico this weekend. Jennifer joined her ex-husband Marc to perform a duet of "No Me Ames" on stage on Friday evening. It was the second to last night of her Dance Again world tour, and the friendly former flames looked happy to reunite for a moment. Casper also took part in the show, as he has all tour long. Jennifer's heart now belongs to Casper, of course, and those two were back to cuddling to watch a charity celebrity football game on Saturday. Jennifer took a seat on Casper's knee when he wasn't showing off his skills with the pigskin. Jennifer's daughter, Emme, joined in on the fun and wore red to match J Lo and Casper's jerseys. Last night was the final show, and J Lo tweeted to her fans, "Thank you for the best 1st World Tour ever!"
