Good-natured scene stealing is nothing new for Pippa Middleton.
Although Duchess Kate and her suddenly-famous younger sister and Maid of Honor, 27, are "best friends" according to one family friend, that doesn't mean they're unlike most siblings. "There is a healthy competition between the two," royal watcher Katie Nicholl says in the new Us Weekly.

"Certainly when it comes to looks, like who is the slimmest or better looking, there is a little friendly rivalry."
Kate, 29, and Pippa squabble over "weird things," says a family source. "You'd see them fight over who had the worst headache or period pain!"
And it's no wonder that Pippa has grabbed headlines for her sexy, elegant style, her chemistry with Prince Harry during the royal wedding -- and startling pics of her partying in a purple bra and a white bikini.

"She was the sister who sparkled," Nicholl, author of The Making of a Royal Romance, says. "She is an extrovert, compared to Kate."
Indeed, as fellow students at posh boarding school Marlborough College, "none of the guys noticed Kate," a source says. When Kate began attending St. Andrews in Scotland (where she met Prince William), Edinburgh student Pippa frequently visited to mingle with her sister's noble new pals.

"She dated a couple of the St. Andrew's lads and tried to get in with a lot of William's friends," the source says. "She wasn't sleeping around, but she flirts with the most well-connected men."

Tell Us What You Think
17kate is much prettier than pippa...and obviously pippa is the s l u t t y one. kate is a lot classier.
@ Celine Jos - Actually, the British press was pretty brutal on Pippa before the wedding. But nice try.
some can say pippa is stunning bla bla.. but kate is the princess material.. thats why kate won william's heart..
Catherine is waaaaayyyyy prettier than pippa n she's got perfect complexion.. I wish my skin as flawless as hers..
The "source" says Pippa wasn't sleeping around, but just flirts...so is that what her picture in her bra dancing with a man in his underwear was? LOL! Sorry, but getting caught in their undies implies she was not just flirting!
geez they couldn't have made the photoshopping anymore obvious?!
All the people saying Pippa is beautiful must be the Brits!
Kate is far prettier then Pippa.
william got the good looking one. her sister is just odd looking.
Isn't Katie Nicholl the liar who has been claiming since like 2003 that a Wills and Kate engagement was "imminent"? She S ucks D ick for cocaine
They are both very pretty with great figures and I'm sure they are best friends. I highly doubt they are immature and squabble at this age. Pippa definitely stood out on the wedding day, but Kate had to have approved that bridesmaid dress! Kate was absolutely stunning at her wedding!
Kate is beautiful & Pippa is attractive. Kate has a great figure & so does Pippa. Kate is way better suited to be the Princess of Wales. LOVE Kate.
Kate has a prettier face, but her sister has a better body and an unattractive face...I don't see why some magazines call her 'stunning'! NOT!
Super. The Daily Royal Story. Glad to see the less desperate, less flirty, quiet girl got the guy in the end. Nice twist.
I also think Kate is more attractive than Pippa but Kate is off the market now and so the dogs are out to make of fuss over Pippa.
Yeah, I think Kate is better looking. But US, are we gonna milk these people to death? Kate's winning the friendly rivalry right now, she has a Prince..LOL.
I actually think Kate is the better looking sister...just my opinion.
