Bill Clinton worked his famous charm on supermodel Christie Brinkley at pharma billionaire Stewart Rahr‘s party. Security at Rahr’s Wainscott estate was tight on Saturday, with guests including Prince Albert of Monaco, Iceland’s President Olafur Ragnar Grimsson, Carl Icahn, Donald Trump, Jonathan Tisch, David Koch, Leon Black, Steve Cohen, Sen. Chuck Schumer, Veronica Webb, David Foster, LL Cool J, Ivanka Trump and Jared Kushner. During Lionel Richie‘s performance, Clinton was spotted having a long and intense conversation with Brinkley. Prince Albert was trying to catch a plane, but Rahr dragged Richie over and had the singer ask him to “stay an extra hour until his performance was over,” a partygoer reports. When Albert declined, Rahr added, “If I donate $1 million to your favorite charity, will you stay?” His Serene Highness replied with a glare, “For the children, I will stay.”
