The Princess and the Ogre

American Ballet Theatre Spring Gala. Metropolitan Opera, Lincoln Center, 6:30 p.m. Scheduled to attend: Caroline Kennedy, Carolina Herrera, Sarah Ferguson (the Duchess of York), Muffie Potter Aston, and others. When she was divorced, Sarah Ferguson lost the title “Baroness Killyleagh.” Who will step forward to lead the people of Killyleagh?
Shrek the Third screening. Chelsea West Cinemas, 333 W. 23rd St., at Eighth Ave., 6 p.m. Expected guests include Mike Myers, Amy Poehler, Amy Sedaris, John Krasinski, Jeffrey Katzenberg, and James Gandolfini. But certainly not Muffie Potter Aston. If she shows up at the door, she’ll be turned away. She knows what she did.
