• Engaged: Alyssa Mastromonaco, 36, and David Krone, 46. Power couple alert! She’s the White House deputy chief of staff for operations; he’s chief of staff to Senate Majority Leader Harry Reid. The betrothal actually happened in late December — a day before before she flew off to Hawaii with the Obama team for the holidays — and we can probably blame the fiscal cliff distraction for the fact that word is only just now getting around town. No date or location for a wedding set yet. First introduced by Obama campaign manager Jim Messina, they have been dating since early 2010.
