Either Christina has an impostor or someone over at the Beverly Hills kids boutique, Bellini, is just trying to get a little free press. An employee from the store told the New York Daily News that Christina and Jordan went on a $3,000 shopping spree together on Saturday. "They seemed really excited,” the worker told the Daily News, “She was talking to [another customer] and she said she took a home pregnancy test and that it was positive. She kept saying they'd have to come back when they knew the sex of the baby.” Christina's rep, however, says it's totally untrue. The singer was flying to Vegas for her NBA All-Star appearance at the time. We doubt it's bothering Christina any, she's much too busy on tour to worry about ridiculous baby rumors.
