George Clooney celebrated his Oscar win for “Argo” at a private dinner with pals, including Rande Gerber. After the awards, he headed to clubby LA eatery Craig’s with his gold statue in one hand and statuesque girlfriend Stacy Keibler on the other. Also at Clooney’s table: Ben Affleck, Gerber’s wife Cindy Crawford, CAA’s Bryan Lourd, producer Grant Heslov and developer Mike Meldman. Said a spy: “Their Oscars were on the table, and they did shots of [Clooney’s] Casamigos tequila all night.”
