Hey, isn’t that… Michelle Obama enjoying another birthday celebration on Friday night, this one a small dinner in one of the private rooms at the stylish Penn Quarter brasserie Poste.

FLOTUS has already marked her 50th with a White House dance party and an intimate dinner at Cafe Milano. Perhaps it’s birthday overkill? Well, there’s no such thing as too much cake — and it’s a big milestone, after all.

Our tipster spotted the birthday gal in a navy blazer and a wide, embellished turquoise scarf/headband (another trend alert?). Multiple plates of truffled frites and at least three birthday cakes were spotted heading into the area where Obama and her crew were dining.
