With partner Richie Akiva, Sartiano runs a handful of celeb-favored nightspots in town, including 1OAK, Butter and G-Spa. He's also the ex-boyfriend of an Olsen twin and of Jamie-Lynn Sigler.

North Carolina native Sartiano moved to New York to attend Columbia. He soon found himself caught up in the velvet-rope scene and started promoting parties at the now-shuttered Life—where he first met future business partner Richie Akiva—while still a student., and the pair opened the Gossip Girl-namechecked restaurant/nightclub Butter in 2002. With Butter's success, Sartiano has since invested in G-Spa, the lounge located in the Gansevoort Hotel, the Star Room in the Hamptons, and the lawsuit-laden venture 1OAK in Chelsea.

The former "man snack" of Lindsay Lohan, Ashlee Simpson, and Ashley Olsen, Sartiano has been linked to Kristin Cavallari, Eliza Dushku, and Anne Hathaway, and Jamie-Lynn Sigler. He was briefly engaged to model Allie Rizzo, but the pair split in 2011. [Image via Getty]
