Fashion mogul Elie Tahari'smarriage to his wife of 10 years, Rory, might be on the rocks, as The Post reported -- but he was all smiles at Bergdorf Goodman on Thursday, when Elle's Joe Zee and Bergdorf VP Linda Fargo threw Tahari a party to help celebrate his Spring 2010 line. While he wouldn't answer questions about his marriage, he did mention that he's been doing a lot of yoga and was friendly with guests. The Post also previously reported that Tahari has quietly been looking to unload $70 million in property he owns with Rory, who is 20 years his junior. -Page Six, NY Post
