“Christina is a wonderful mother and was not present in the park when Max fell and hurt himself,” he wrote. “To imply that she had something to do with this incident, without any investigation on your part whatsoever, is reckless and unconscionable."
The firestorm began when MediaTakeOut.com published the with a blaring headline.
“CHILD ABUSE???? CHRISTINA AGUILERA'S SON IS PHOTO'D WITH A BLACK EYE!!!"
MediaTakeOut.com proceeded to delete the “Child Abuse” statement from the headline.
