One of a Kind: Formerly a gallumphing Sloaney girl, as nanny to the royal princes - and currently general royal factotum at large - Tiggy was (see Appearance below) typical of the invisible (read: plainish) celebrity nanny. See also the former Yates-Geldof helpmeet, plus assorted fat/pasty/invisible "face in the crowd" types, walking two steps behind celebs on arrival at Heathrow, who turn out to have sole responsibility for the superstars' greatest achievements.
Appearance: Tiggy 1: Plump, adenoidal Sloane, posing absolutely no threat. With her mousey hair, jolly-hockey-sticks dress sense, and Balmoral buffed cheeks, Tiggy seemed to personify a jolly nice, cake-bingeing Jilly Cooper heroine. Tiggy then lost weight. Tiggy 2: Slender, bulimic-irritant with piste-pink complexion and natty, knee-length, Di-style suits. Deb of the Year meets temp recruitment agency model.
Piste Off: Replaced in the chair-lift by the iron-jawed grin of Tara Palmer-Tomkinson on the recent royal jaunt to Klosters, much was made of Tiggy's apparent fall from grace. Life is hard.
Upstart: Her Tigginess was famously thought to have narked the Queen of Hearts by appearing to replace her in the princes' affections. Tiggy then had a jolly good ticking off last year after being photographed cuddling Harry, who is apparently considered too old for such public displays of affection. The Empire never really stood a chance after Dr Spock.
Family Matter: The family Legge-Bourke, forever discreet, has a proud royal past. Tiggy's mother, Shan Legge-Bourke (only in England... ), is a lady-in-waiting to Princess Ann. After Montessori training and nursery experience, Tiggy was recommended for a post with Prince Charles by his godmother, Lady Susan Hussey.
Fame Prospects: Tiggy will probably shepherd some sprig-frocked, titled girlies, marry a silver stick in waiting, and then produce a brood of ruddy cheeked infants with names like Harry and William. Alternatively, she could become a PR and stick on name labels in press tents. Fame does not sit prettily on our Tiggy. Leave all that kind of stuff to Tara, Marina and Diana.
