Pop star Christina Aguilera has fuelled speculation she is pregnant - by filling up with glazed donuts on a recent visit to Australia. The singer, who is rumoured to be carrying husband Jordan Bratman's baby, arrived at Sydney airport on Sunday night (22Jul07) from Brisbane, before ordering her limousine driver to make a brief stop at a local Krispy Kreme outlet. Bratman is reported to have bought a large box of mixed donuts for the star, who was photographed with the snacks in the back of her luxury vehicle. Earlier this month (Jul07), Aguilera's estranged father Fausto 'confirmed' the pop star was pregnant.
