Lopez is promoting her new album, "Brave," in London. 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.
