Gossip columnists are having a field day speculating that Jennifer Lopez and Sean "Puffy" Combs have ended their romance. The rumors kicked into high gear when Lopez failed to show up at Combs's Labor Day bash in the Hamptons over the weekend, days after the New York Post reported that Combs recently was spotted with a Latina beauty who was not Lopez. All eyes are on Thursday's MTV Video Music Awards, in which Lopez is a multiple nominee.
