Engaged: White House chef Sam Kass and MSNBC’s Alex Wagner. The two managed to keep their year-long romance a secret until we reported it last month; they made it official in past week or two. Big giveaway: The pretty diamond ring on her left hand that caught a few eyes recently. Kass, 33, is the Obamas’ personal chef and “Let’s Move” ambassador; Wagner, 35, is the brainy political analyst, MSNBC host and Washington native.
