Danica and friend

Who is this slightly roomy woman always seen with Danica? What position does she hold that makes her so important that she would be the first one on the scene after Danica won in Japan to give her the first congratulatory hug? Is she PR?, or more of a "handeler"? Afterall, we did see her sprint down pit-lane at the Indy 500 in 2008 to stop Danica from making a fool of herself as she went to scold Briscoe after their pit exit coming-together. Or could she be someone even closer?
