Singer Avril Lavigne, who at the end of September denied speculation that she was pregnant after being photographed in a big, figure-hiding shirt, might have fueled further speculation by repeating the wardrobe choice Wednesday’s Jingle Ball concert at Wells Fargo Center in Philadelphia.

September speculation came after paparazzi photos showed Lavigne with boyfriend and former "The Hills" star Brody Jenner, wearing a very loose-fitting top. Lavigne scoffed at the suggestion on the television show “Access Hollywood Live,” saying she was insulted by it. But at Jingle Jam, Lavigne again was wearing an oversized, loose-fitting shirt, which occasionally clung to what appeared to be a larger midriff than the petite, 27-year-old singer is known for.
