The New York Post reports Shar Jackson is claiming that Britney Spears is pregnant with the child of her ex-fiance, Kevin Federline. While shopping at Dolce & Gabbana on Rodeo Drive, a spy said Jackson kept getting phone calls from Federline. She repeatedly hung up on him, saying, "Yuck. He is so annoying!" She then was overheard saying, "You know, Britney's pregnant." Britney's rep said, "As far as we know, Britney is not pregnant."
