The actress-turned-fashion designer was sporting a make-up- free visage on her arrival at JFK airport on Sunday night, with her tan suggesting she may have been returning from a sun-filled vacation.
Despite being papped in a far less forgiving state than she's used to, Mary Kate looked happy and relaxed.
It's good to see the young fashionista didn't try to hide her — shock, horror — natural complexion behing a giant pair of sunglasses .
Perhaps it's all the loving she's been getting from her new man. Mary Kate's currently dating Olivier Sarkozy — ze 'alf-brother of ex-French President Nicolas Sarkozy.
He's 17 years her senior but judging by MK's carefree attitude in this pic, he knows how to treat a girl right!
Or maybe she's been enjoying the good life since "officially retiring from acting" last year.
