Ed Bass knows how to keep a secret. While in Aspen over New Year’s weekend, the billionaire and Vicki Skinner told friends that they were just going shopping. What they actually did was slip off to a small local wedding chapel. The newlyweds concealed their big news until just last week. Bass made the announcement at the Texas home of Van Cliburn. A night earlier, Bass’s Botanical Research Institute of Texas threw a gala for 600 at Fort Worth’s Worthington Hotel to honor Costa Rican president Jose Maria Figueres.
