Mary-Kate Olsen

Mary-Kate Olsen and Nate Lowman have been together a long time, and have maintained a relatively low-key, seemingly stable relationship. Impressive.

It's over now, though.

The actress-design mogul confirmed her split from Nate Lowman, Us Weekly reports, quoting their rep saying, "No, they are not [together]. It’s been a while."

That settles that.

Nate Lowman had a good run as Mr. Mary-Kate.

Olsen and Lowman began dating in 2008 after meeting through mutual friends. There were rumors he got her pregnant and in late 2009 that they got engaged.

Neither happened.

Last year, her rep told Us that celebrity gossip rumors that the two are engaged were "untrue." Not only that, they possibly were not together at all then. Oh well.

Here's wishing both the best in their return to the dating scene.

A ring buried in a box of chocolates. A popped question over a romantic dinner in Paris. A tearful acceptance and applause from a moved crowd of diners.

That sounds great, but despite recent celebrity gossip reports, it did not actually take place between Mary-Kate Olsen and her boyfriend Nate Lowman.

Olsen, who has been dating Lowman since 2008 after they met through some mutual friends, is neither engaged nor preparing a prenup with her love.

"Even though this information continues to be reported as 'fact,' the stories regarding Mary-Kate being engaged are not accurate," Olsen's rep said.

The actress-design mogul and her beau, who was rumored to have gotten Mary-Kate pregnant last December, recently attended Paris Fashion Week.

But no marriage plans, at least not yet. The only engagement she has on tap is to star in Beastly, alongside Neil Patrick Harris and Vanessa Hudgens.

Nate Lowman has no plans to be Mr. Mary-Kate Olsen. Yet.

Following an evening of incredible fashion at the Costume Institute Gala at The Metropolitan Museum of Art last night, we've been matching up celebrities in a series of fashionable face-offs.

And no relationship is safe from this competition!

Gossip Girl co-stars Leighton Meester and Blake Lively were pitted against one another earlier in the day... but that's nothing compared to the match-up below!

Sisters Ashley Olsen and Mary-Kate Olsen were spotted on the red carpet, each at her thin, unfashionable best. Compare the siblings below and then vote in our poll:

Who looks better?

What a year for plastic surgery. Despite having achieved fame and fortune already, many celebrities just can't resist going under the knife. Just look at this guy!

What a freak. But here we're focused solely on 2008 and some of the best (and worst) unnecessary surgeries performed on stars in the past 12 months.

Leading the way - and following in the talentless, surgery-loving footsteps of little sister Ashlee - is our girl Jessica Simpson. Her gigantic boobs may be all-natural, but no way that schnozz is. Absolutely none. Girl had that thing shaved down.

Look at two sets of Jessica Simpson pics from 2008 (left) vs. before ...

Skinny star Mary-Kate Olsen has sparked rumours that she is expecting her first child after her weight shot up to a practically-obese 102 pounds.

A source tells the National Enquirer:

"Mary-Kate has been looking a lot rounder recently. It is good she has put on weight, because she previously suffered from anorexia, but a lot of people think she could actually be attempting to hide her pregnancy."

Mary-Kate Olsen has been dating artist Nate Lowman since early this year and is said to have been inspired to start a family by her friend, Heath Ledger - who told her that becoming a father was the most rewarding thing he had ever done.

A source added: "Mary-Kate really took Heath's words to heart. She wanted the same kind of fulfillment in her life that Heath found in his after becoming a dad."

But is she really pregnant by Nate Lowman, or are we jumping the gun based on her consumption of the occasional cheeseburger? What do you think?

Hey, at least they only need one chair and are doing their part to conserve the world's food supply. We should be lauding these skinny celebrities as humanitarians.

Mary-Kate Olsen and Mischa Barton cozied up at the landmark Grand Opening of Atlantis, the Palm Resort, and the Palm Jumeirah in Dubai, United Arab Emirates.

She may not be ordering many burgers, but Mary-Kate finds new boyfriend Nate Lowman delicious. Mischa hasn't swallowed anything since her Cisco Adler daze.

Star Magazine, also known as the beacon of celebrity news integrity, has a great story this morning - that Ashley Olsen is contemplating getting some larger breasts and trying to persuade twin sister Mary-Kate to get them as well.

“Ashley is considering getting her boobs done - she wants to be more voluptuous," reports a supposed insider. "And she told Mary-Kate that she wanted her to get one at the same time so that it wouldn’t be glaringly obvious."

The article continues: "That way, they could say that they had just both matured and were filling out naturally.” Mmm hmm. Just like Audrina Patridge.

Mary-Kate Olsen, according to the report, is not a fan - she is “horrified” by the idea and “hates being told what to do and how to look by Ashley.”

NOTE TO THE OLSEN TWINS: If looking "voluptuous" is really the goal, you might start with a little nourishment. Seriously. Try the bacon cheeseburger the next time you're out. Not only will it "fill you out," but it will piss off PETA.

They really do. And we're not talking about eating disorders, drug problems, the worst fashion sense on Earth, or tangential connections to the death of a prominent actor earlier this year. We mean it in the literal sense!

Check out this Olsen Twins photo and see:

No word on whether Mary-Kate and Ashley were returning from a three-week African safari, or a trip to the grocery store. Or whether the bodyguards have the other two-thirds of their stuff. Or why they're wearing sunglasses inside.

We could go on. Instead, we invite you to check out the Shannon Twins instead. We think you'll find them slightly more stimulating than these trolls.

... you know. Oh please. Cut the crap. Do not even act like you don't know what we're talking about or you're above it. We both know you'd go there.

The only question is:

Who would you rather ...

... you know. Both are kinda cute. Neither is super hot. Both are on the celebrity fashion police's most wanted list. Neither enjoys a nice meal. If you were given a choice between Nicole Richie or Mary-Kate Olsen, tell us...
