This is one way to work out trouble in paradise! Jennifer Lopez's beau Casper Smart is continuing to fight off rumors that the couple is splitting - this time with a playful Twitpic of the twosome sword fighting in front of The Colosseum in Rome yesterday. Casper tweeted: "Fighting with real #gladiator swords in front of the #coliseum in #rome what's better than that??" But are the diva and her divo just trying to make is seem like everything is a-okay?!
