Long-distance relationships can be tricky and no one knows that better than fashion's newest power couple Mary-Kate Olsen, who lives downtown (near Tribeca we believe) and Olivier Sarkozy, who lives all the way...uptown. To close this insurmountable gap in their relationship (although that age one wasn't much of an issue), Sarkozy sold his Upper East Side townhouse earlier this year for $8.4 million and had been renting a place in Chelsea until he found something further downtown--a townhouse "below 14th" to be exact--to be closer to MK, Pages Six is reporting: But it seems Sarko has now found hipper digs further downtown, in which he can entertain his billionaire, 17-years-younger, child-star-turned-fashion-designer gal pal. In the footsteps of Alec Baldwin, he’s following the trend of older men moving downtown to satisfy the tastes of their younger, more energetic girlfriends. Yes, that must be what he's doing.

This morning, the UK's Daily Mail published a story that is headlined "Make-up free Ashley Olsen is unrecognisable in casual jeans and a shirt as she shares a smoke break with mystery man." However, the four pictures that accompany the article, each of which are captioned with Ashley's name, are all clearly of Mary-Kate (a lack of makeup is no excuse). To make matters worse, at the end of the story, they include a picture of the real Ashley Olsen with the caption "Usual style: Last week Mary-Kate was pictured taking her dog for a walk in an Amish-inspired white shirt and navy blue circle skirt." The thing is, that outfit is so Ashley's "usual style." What is particularly ironic about this mistake is that, in these photographs, each girl's outfit is an unmistakable representation of its wearer's style. This kind of mix-up was forgivable from the ages of 0-16 when they basically just wore the same outfits in different colors to every appearance, but now the recently-turned 25-year-old fashion designers have developed their own distinct way of dressing. Without studying their facial features (which look identical to me, even though they're fraternal), I can identify an Olsen in a snap based on what she's wearing. So, I've put together a guide on how to tell the Olsen twins apart based on their style, since there will obviously be several critical points in your life when you'll need to have this ability.
