Shortly before Christina Aguilera filed for divorce, she went to Cedars Sinai Medical Center for what was described as bumps and bruises and a cut lip. She told the people at the hospital she had fallen down. After she was admitted, her doctor arrived and stitched up the cut.
This is an interesting twist to the whole divorce drama, because it was shortly after this hospital visit that she filed for divorce. The report is in Radar and they don't actually say that Christina did not fall, but they do talk about the open marriage Christina and Jordan had, and that perhaps Jordan became jealous of the women Christina brought home.
