"I got involved in something I should have had no part of," Alba said in a statement. "I realize that I should have used better judgment, and I regret not thinking things through before I made a spontaneous and ill-advised decision to let myself get involved with the people behind this campaign. I sincerely apologize to the citizens of Oklahoma City and to the United Way for my involvement in this incident."

Alba is currently in Oklahoma City filming The Killer Inside Me with Kate Hudson and Casey Affleck. Oklahoma City spokeswoman Kristy Yager estimates the damage between $500 and $700 -- not enough to earn Alba jail time if she were to be charged or convicted of a crime.
