Britain's tabs have become sops to the story of Pippa's "global brand" as "Her Royal Hotness." And as the kudos keep piling on Kate's striving sister, the commentariat is getting fed up with Her Royal Butterface. Seems Pippa's one of those girls that makes some men inexplicably caterwaul -- to the befuddlement of many women. To wit:

"Why does she look so old?,'' sniffs someone named Anna at the Daily Mail.

"Pippa is a merchandising media tool; I wish you'd stop shoving her down our throats," snarls "ex-pat" Kara Lamb of Los Angeles on the Daily Mail.

"She is no one special. Not by a long shot."

And snips DoreenMoles of San Diego: "She's way too big for her boots, and the press and papers constantly taking photo's and writing articles about her are only feeding the needs of this silly little social climbing girl. Her Mum & Dad need to take her in hand, she's becoming an embarrassment to them. She needs to DISAPPEAR and do it now."

Alas, there is little likelihood of that happening now that the tabs claim Pippa has set her sights on Prince Harry. Seems the Royal wannabe has been spied sharing an afternoon tea and biscuit with Britain's Hitler-inspired Windsor, which apparently passes for foreplay in Britain.

"Has single Pippa her eye on Harry?," one tab inquires. "Pippa Middleton and Prince Harry have 'chemistry,' " claims another.

Pippa has dumped her beau, ex-cricketer Alex Loudon, and been snapped with former boyfriend George Percy. He is heir to the dukedom of Northumberland and a $600 million fortune. And some speculate that Pippa really aspires to be Her Grace The Duchess of Northumberland, for Percy's rich enough to give Pippa an edge in her contest with Kate.

A word to the wise: paste on your stiff upper lip. Because all we can be really sure of is this perky upstart isn't going away.
