Christina Aguilera is on the verge of a personal crisis. Family and friends are worried about the singer’s health as she went back to the LA eatery where she got drunk only three days before. A fellow dinnergoer at Osteria Mozza, told US magazine, “She acted as if the arrest never happened. When their server offered them dessert, they asked for more wine.” Another source said Christina has turned into booze and food to cope with her sadness after her divorcer with Jordan Bratman. “Christina’s lost her confidence since she split from Jordan,” an insider said. “She gets terribly sad, and that’s when all the awful memories come flooding back and she ends up numbing herself with booze and food.”  “She needs to get help before something even more serious happens,” added the source.
