Mary-Kate Olsen was seen walking around New York City in some very interesting footwear yesterday. She had lunch with boyfriend Nate Lowman, but the two left the West Village restaurant spearately. Nate took off on his bicycle while MK lit a cigarette and walked home.

I’m not liking the giant black shirt and drop crotch pants Mary-Kate has on. I think they’d work separately, but together they just look messy. I love the shoes though! How does she even walk in them?

However, the girls weren’t in London for very long. Earlier today, they were spotted catching a flight back to NYC with none other than Gwyneth Paltrow! I love Gwyn’s oversized scarf. All three ladies looked chic, casual and lovely as they strolled through Heathrow airport.

MK has a different attitude for the paparazzi recently. Instead of hiding her face and using her bodyguards to shield herself from the cameras, she just stood patiently while collecting her luggage as the camera snapped away. She has a ton of luggage with her!

Nate is with her. It looks like their relationship is getting serious! I’m happy for MK. She seems to be in high spirits lately.

What fashion shows do you think Mary-Kate is going to attend?

Ashley and Justin were seen having a romantic dinner at Stack. According to E Online, the pair dined on “shared yellowtail sashimi, spicy wings and black cod miso lettuce cups.”

After dinner, they headed over to popular nightclub Jet with several friends.

The couple wasn’t shy about their PDA. Quite a few onlookers spotted the pair on the dance floor and said they seemed to be having a good time!
