Christina Aguilera says she’s not responsible for a giant bruise on her son’s face.

Christina was snapped leaving LAX yesterday with a bruise on her three-year-old son Max’s face, and rumors began to fly that it had to do with her “erratic behavior and alleged booze-filled outings.”

But sources told TMZ, that’s total nonsense. They allege Max was out with his nanny last week, chasing around squirrels, when the kid tripped over a rock and bruised his face.

Max was taken to the doctor immediately and everything was fine. No broken nose, no stitches. Just your average boyhood bruise.

She just attempted to shove his face under a blanket, in order to avoid all the nasty speculation.
