Kate, and for having the most famous derriere since Kim Kardashian.
But there's a lot more to her besides her royal connection and celebrated posterior.
Here's the untold truth of the Duchess of Cambridge's famous sister.
What's in a nickname?
Philippa Charlotte Middleton was born in 1983 in the English town of Redding.
The nickname Pippa comes from her first name, and it's what she goes by everywhere.
British tabloids, who are fascinated with her, coined a nickname for her group of friends
— The Pipparettes.
As a child, classmates called her "Perfect Pippa."
But some also reportedly gave her a much less flattering nickname by calling her "Panface,"
because of her face supposedly...looking flat?
Kids are harsh, even when you're the sister of a future princess, but at least the negative
attention prepared her for the level of scrutiny that would come later in life with so much
media attention.
"It's been a bit difficult, ya, ah..it's ah getting..
It's sort of getting used to not being entirely private feeling that wherever I go someone
will spot me."
Before the fame
Prior to becoming known as a socialite with friends in high places, Middleton worked in
public relations for Table Talk, a catering business.
She also worked for her parents' party supply business and was involved in creating a blog
for the company's website.
Pippa's since used her writing skills to pen pieces for Vanity Fair and a party planning
book, the latter of which was, unfortunately, widely mocked.
The dress heard 'round the world
In 2011, Pippa Middleton became the world's most famous bridesmaid while wearing a Sarah
Burton by Alexander McQueen white dress at her sister Kate's wedding to Prince William.
There is an etiquette rule that nobody but the bride should wear white at a wedding,
because it will upstage the bride on her special day.
But despite the color choice, that's not why Pippa's dress got so much attention.
It was because, when she was holding her sister Kate's long wedding dress train, everybody
got a good view of her backside, which was accentuated by the tight dress.
The dress made her known in the press as "Her Royal Hotness."
She acknowledged in a 2014 speech, saying that "fitted a little too well," and showed
a sense of humor when she talked about the notoriety the dress provided her.
"As I have found out, recognition has its upside, its downside and — you may say — its
backside."
Turning to TV
In 2014, Pippa was reportedly being considered for a correspondent spot at NBC right around
when she was spotted showing up with a camera crew to do some country dancing in Jackson
Hole, Wyoming.
The word was the clips were part of a tryout for the show, but the British tabloid The
Mirror eviscerated her, insinuating that "she failed to impress channel bosses with her
test shoots," and calling her dancing "cringeworthy."
Looks like she also foreclosed any opportunity to use her fame for a place on Dancing with
the Stars in one foul shake.
Faking the cake
In her own way, Middleton is trying to make the world a better place.
She's raised a lot of money for charity with the fitness events she's competed in.
And she wrote a healthy recipe cookbook in 2016 called Heartfelt, with the money earned
designated to go to the British Heart Foundation.
Of the recipe book, she told The Daily Mail, "'People see me as someone privileged who
has used my position to advantage; that I don't really work, that I am a socialite — that
word really irritates me."
But then she made the mistake of being a little too honest about how the cookbook came together.
She told The Mirror, "I would like to say I have made every single one, but I have definitely
done a good 80 percent of them."
Those culinary shortcuts were certainly a disappointment to some fans.
Getting hacked
In 2016, Middleton became the latest celebrity to have her iCloud account hacked, although
unlike Jennifer Lawrence and Kate Upton, her photos have so far not been released.
Reportedly 3,000 photos were stolen, many of her famous sister, the Duchess of Cambridge,
her niece Princess Charlotte and nephew Prince George.
The reported hacker was arrested after trying to shop around the pix.
Middleton went to court in the UK to prevent the photos from being released and a court
agreed.
On, off, and on again to engagement
Kate Middleton and Prince William were on-and-off for some time before they finally married
in 2011.
Pippa followed in her sister's footsteps by getting engaged to on-and-off boyfriend financier
James Matthews in July 2016.
She first dated Matthews in 2012, then hooked up with investment manager Nico Jackson, then
got back together with Matthews in 2015 after that relationship ended.
She was then spotted with him on vacation and at numerous charitable endeavors before
their engagement.
Matthews reportedly surprised Middleton with the proposal, which happened in England's
Lake District.
But he didn't surprise her parents — he asked them first before popping the question.
Her engagement ring has been described as an "Art Deco design" which is both "practical"
and "timeless."
Pippa and James have something in common — both have famous siblings.
James' brother Spencer is on a British reality show about rich young adults called Made in
Chelsea.
Staying centered
While Princes William and Harry were born into royalty, Pippa and her sister Kate had
a comparatively ordinary upbringing.
According to Pippa, they've managed to maintain the connection they had from the start, despite
her sister's new title and the attention that's come with it.
"We have a very normal sisterly relationship we're very close and you know we support each
other and get each other's opinions and things."
