Christina Aguilera split her lip after 'a simple fall,' according to sources.
Earlier, reports suggested that Aguilera might have been a victim of domestic violence, since she busted her lip the very same day she filed for divorce from Jordan Bratman.
However, sources connected with Aguilera said she split her lip last week after "a simple fall."
"It''s as innocent as that," TMZ.com quoted a source as saying.
