‘Social’ times in St. Tropez

Facebook co-founder Eduardo Saverin has been living large in St. Tropez, checking into the $8,000-a-night presidential suite of the swanky Hotel Byblos and party-hopping with a group of friends and an even larger gaggle of models, sources told Page Six. Saverin, played by Andrew Garfield in the hit movie “The Social Network,” flew his pals from Singapore, where he’s currently living, to the French Riviera in July, promising an extended party. And he didn’t disappoint. Saverin, who holds an estimated $2.5 billion in Facebook stock, arrived at Bagatelle Brunch in Nikki Beach on Saturday with three mates and 10 leggy models. The young Brazilian-born entrepreneur, who spent about $50,000 on Cristal, was spotted sipping the Champagne from the bottle, and his pals were seen spraying their attractive friends. A hotel staffer confirmed Saverin and his posse checked out over the weekend.
