Manchester - "Saw its backside, like, and had to call it Pippy," was the lame explanation ahead of the two year-old's debut at Chester racecourse on Wednesday.
The Australian Exceed And Excel-sired colt out of US mare Night Shift was snapped up by Wayne Rooney for £63,600.
A passing resemblance to Pippa Middleton's arse caught the Man U striker's eye at a bloodstock auction shortly after Christmas.
But it was a full week before he twigged he'd bagged a colt and not a filly.
A surreptitious glance at Pippy's rear quarters by QM-NewsCorpse stringers confirms the sleek and glossy hind quarters look somewhat androgynous.
But one swish of its chestnut tail reveals some pretty impressive wedding tackle that's set to carry on growing for at least a year ahead of next year's Epsom Derby tilt.
This Wednesday the colt takes on thirteen rivals at Chester's opener the Lily Agnes Stakes with jockey Jamie Spencer set to sport Wayne and Coleen's pink and white silks.
Fellow Man U striker Michael Owen, co-owner with the Rooneys of the Manor House Team's runner, sees their syndicate sponsor the 2.15 race which bullish trainer Tom Dascombe fancies for a win.
Their two other hopefuls Switcharooney and Tomway are entered in all the major races for two year-olds including several at this year's Royal Ascot.
At 33/1 Pippy's Chester debut looks like a steal.
