A two-metre portrait of the superfan is to be displayed at the city's art gallery - home of arch rivals Saints.
Artist Karl Rudziak, from Pembroke Road, Old Portsmouth, spent eight months painting the larger-than-life version of Mr Westwood.
And after being picked to hang at the National Portrait Gallery in London it will now go on tour as part of the prestigious BP Portrait Award.
Mr Westwood, from Petersfield, said: 'I just hope nothing happens to it, for Karl's sake, but for me it's a bit tongue-in-cheek - Pompey at Southampton - for me it's quite a nice little wind-up.'
The work will be displayed at the Southampton City Art Gallery in Commercial Road, Southampton, from tomorrow until November 22.
