I am afraid I am not getting the true colors reference and allegations of Pippa taking advantage of anything.
While I certainly agree that it makes sense to have an experienced Lady in waiting when joining the royal family...at some point when she becomes more familiar in her new position, why shouldn't Kate choose someone she has a relationship with (whether that be by blood or just friendship). She wouldn't be the first.
And since the wedding, maybe I have missed something...but I haven't seen Pippa once. So how is she taking advantage.
Now don't get me wrong, there has been alot of publicity....old pictures taken YEARS ago on a boat, and at a party...but how is SHE seeking publicity? Its more like people who knew her, her taking advantage and selling old pics of her. That's hardly her fault.
At this point, its like the tabloids are just making up stories and throwing in her name and people are running with it.
