She's not a royal or a celebrity but Pippa Middleton is certainly treated like one, and that's causing a problem between her and her sister, Kate.
According to a report in the UK's Mail on Sunday, Kate and her husband, Prince William, have asked her younger sister to lower her profile.
"Pippa has been asked to tone it down," a friend of William's brother, Prince Harry, tells the newspaper.
The royal couple, who are expecting their first child next month, are said to be concerned that Pippa's leaving herself open to criticism by acting like a celebrity.
Since she became a royal sister-in-law Pippa has written a party planning book and become a contributing editor for Vanity Fair magazine, and she's regularly seen at the hottest parties in London.

The palace was reportedly displeased when Pippa used her fame to secure a book deal, and even more unhappy when she was photographed last year with a friend who pointed a fake gun at the paparazzi.
Kate doesn't want to cause any embarrassment to the Queen and an insider tells In Touch that "she has been having lots of very serious heart-to-heart chats with Pippa and reminding her that she can't live her life as she did before Kate married William. She needs to keep her head down and not do anything that will cause any more embarrassment."
A friend tells the Mail on Sunday that the 29-year-old is trying to do as her sister has asked. "She's been strategically scaling down the amount of times she is pictured at launches, especially clothing launches," the friend admits. "She is trying her best to avoid the cameras where she can."
