Mary-Kate Olsen and her boyfriend Nate Lowman were spotted grabbing coffee on Thursday morning. Later that day, MK would be seen at LAX airport with her sister, Ashley. Mary-Kate and Nate seemed to be in a rush - I guess MK was trying to get to the airport! - and MK appeared a bit put off by the cameras.

Mary-Kate looked quirky and cute in her motorcycle boots, leather jacket and Indiana Jones-inspired hat! I recently bought this faux leather jacket because I’ve been liking MK’s leather look for a while! Admitting this makes me feel a little silly!

I wonder what Mary-Kate and Ashley are going to be up to in Los Angeles? Hopefully some press for the Row menswear line and Elizabeth & James’ Fall 2009 line!

After attending the Costume Institute Gala this Monday night, Mary-Kate and Ashley Olsen hit the after-party at Bungalow 8, one of their favorite New York City nightspots. Ashley’s boyfriend Justin Bartha joined the girls there too.

Ashley and Justin didn’t change from their Gala wear. I hope Ash took good care of her pristine white dress! Can you imagine going to a nightclub wearing that? I sure can’t!

Mary-Kate changed out of her vintage LaCroix dress. I don’t blame her. While the dress was beautiful, I’m sure it’s not the best thing to be wearing for a fun night out!

MK and Ashley have both been spotted out and about in NYC this week. I don’t have access to them, but you can see MK running errands in Soho here and Ashley hitting the gym near her apartment here.

Mary-Kate Olsen opted for period glamour as she donned Lacroix at last night’s Costume Institute Gala. The dress, adorned in metallic lace and silver-embroidered bustier-basque, was definitely a bold move and I think MK pulled it off.

This year’s theme was “The Model as Muse: Embodying Fashion”, which celebrated the Metropolitan Museum of Art exhibit of the same name. The exhibit celebrates the role of the model in fashion, as a model, a muse and more. It’s supposed to be spectacular, so if you’re in New York any time soon, be sure to check it out.

MK and Ash opted for very different looks this year. Whose do you like better? Whose would you be more inclined to wear? And why didn’t Nate come?

Ashley Olsen looked positively regal at last night’s Costume Institute Gala. She stepped out in a long white dress that was very demure in the front, but had a sexy and dramatic back. Ashley walked the red carpet with her boyfriend Justin Bartha, who cleaned up nicely in a tuxedo!

Tons of stars came out to celebrate the event and the fashion was spectacular! Pop Sugar did a great job of covering nearly every starlet who stepped out last night, so if you want more coverage, be sure to check it out!

Ashley Olsen and her boyfriend, Justing Bartha, attended the 8th annual Harry Josh’s Spring Fling bash at the Gramercy Park Hotel in Manhattan on May 2nd. Harry Josh is a celebrity stylist and the star-studded bash was sponsored by Sveda.

Other attendees included Gisele Bundchen, Tom Brady, Sarah Paulson, Cherry Jones, Lorenzo Martone, Marc Jacobs, Goldie Hawn, Liv Tyler and Kate Hudson.

Ashley looks cute in a pair of cords, her current favorite flats, and a black top, sweater, bag and hat. Ashley hid her face as she dashed from the party to her car. She was hoping to avoid the paparazzi and did a pretty good job, as there are very few pictures of her!

Mary-Kate and Ashley Olsen both looked smashing at the Art of Elysium presents Bright Lights New City event at the Jane in New York city on May 1st. The party featured a performance by Santigold and saw guests such as Vanessa Traina, Ciara, Milla Jovovich, Agyness Deyn and Eva Mendes rocking out for a good cause.

The event was a New York City first for the Hollywood-based charity. The Art of Elysium connects artists and musicians with children battling serious diseases and gives them an opportunity to learn about and explore different creative outlets. The evening was co-hosted by Joy Bryant and raised a lot of money for a worth cause.

MK looked stunning in a menswear tuxedo jacket, original booties and a pink snakeskin clutch. The clutch matched boyfriend Nate Lowman’s pink and purple tie-dyed shirt! Ashley opted for a more casual, yet more classic look with black jeans, a white tank and a grey sweater. I’m so happy to see Ashley out and about again, I’ve missed her!

Ashley Olsen was one of several celebrities who came out last night to attend the Cartier 100th Anniversary Party. The party was held at Cartier’s flagship store on Fifth Avenue. Every attendee left with a bright red goodie bag. I wonder what is in them?!

Cartier, a french jeweller founded in 1847, was celebrating its 100th anniversary in America. They want all out with a swanky, star-studded party! I’m disappointed Ashley didn’t walk the red carpet pre-party, but am glad we caught a glimpse of her outfit as she left.

Other attendees included Anne Hathaway, Demi Moore, Eva Mendes, Kate Hudson, Justin Timberlake, Patti Smith, Rachel Weisz and more. All the stars were decked out in their very best - you can see a slideshow here!

Immediately after attending the Tribeca Film Festival Women Filmmakers Brunch on Thursday, Mary-Kate Olsen joined her sister Ashley Olsen for the 16th annual Women of Distinction Luncheon.

The luncheon, which was held at the Waldorf Astoria, honors women who have made a difference in film and television arts. They were founded in 1993 by the Hollywood Chamber of Commerce.

Mary-Kate Olsen did some jury duty yesterday as she presented at the Tribeca Film Festival Awards Night party. Mary-Kate was joined on stage by Debra Messing and the two of them unveiled the winner for the category they judged, Best Narrative Short.

The 2009 winner of Best Narrative Short was The North Road (La route du Nord),, a film by Carlos Chahine from France.

“We ultimately chose the winner for its poetic, truthful and unsentimental portrait of an exile’s return home to deal with his father’s death 20 years earlier,” the jury said in a statement. “The director, Carlos Chahine, portrays the absurdities and contradictions of how we deal with grief through humor, freshness and subtlety.”

MK was very vocal in the press about how honored and pleased she was to be a jury member. I hope she thoroughly enjoyed the experience!

Lots of great films, filmmakers and actors were honored at the ceremony last night. You can see a complete list of winners here. The film festival continues until May 3rd.

Mary-Kate Olsen was one of several celebrities and Tribeca Film Festival jurors who came out this afternoon for the Women’s Filmmaker Brunch. The event, which was held at City Hall in NYC, celebrated women in film and women filmmakers. Other attendees included Debra Messing, Julianna Margulies and Parker Posey.

MK looked great in her leather jacket, black booties and hot pink paneled skirt. I’m loving the bursts of color she’s been wearing recently. She chose purple for the Matthew Williamson for H&M launch party earlier this week. The simple no-fuss makeup and hair cap the look of perfectly.

I love that MK is a Tribeca Film Festival juror! She’s been out and about so much lately. I only wish I could say the same for Ashley. Ash has been laying really low in Los Angeles these past few days
