Daniel Boulud is getting married later this month. We hear the world-renowned New York chef with three Michelin stars is tying the knot with his younger girlfriend, Katherine Gage, at Relais & Chateaux property Glenmere Mansion in upstate New York. Boulud was married to Michelle “Micky” Palmer Boulud for 23 years, until they divorced in 2010. He recently told Canada’s Globe and Mail they split because, “We didn’t want to be so passive about each other.” Boulud explained that Gage, who worked for him for several years but now runs a foodie Web site, “keeps me young.” A rep for Boulud didn’t get back to us by press time. We really want to know who will be cooking up the wedding banquet.
