Is Jennifer Lopez pregnant or not???

First Jennifer Lopez is pregnant and then she isn't ... what is it going to be??

The New York Post had this to say. DENIALS yesterday by Marc Anthony's rep that Jennifer Lopez is pregnant won't likely squelch the talk. Sources close to the singer's camp are buzzing that she's indeed expecting after years of in vitro. Lopez is promoting her new album, "Brave," in London, where the tabloids have gone to town with the rumors. They report that just before arriving at the Dorchester Hotel, Lopez faxed over a request for just the sort of things a mom-to-be might need - including two humidifiers, two fans, a room set at 80 degrees, Jo Malone candles, white or red roses, soft-baked chocolate chip cookies, sour cream and onion chips, regular chips, veggie platters, plain M&M's, sunflower seeds, Ritz crackers, Dentyne Ice gum, spicy brown mustard, mayonnaise, Smartwater, caffeine-free Coke and Red Bull. A rep for Lopez said she didn't know if the singer is pregnant.
