The couple are due to marry on Saturday (29.07.06) in exclusive French town St Tropez - but the marriage could be unlawful.
A St Tropez town hall spokesman said: "Anyone wishing to get married in St Tropez must be a resident here for one month before the wedding." The former 'Baywatch' actress and the singer are said to be tying the knot aboard a friend's yacht.
Pammie - who wore a bikini for her wedding to Tommy Lee - will wear a white dress and carry pink and white lilies.
Her close friend photographer David LaChapelle will be the 'maid of honour', according to Us Weekly magazine.
After the nuptials, the wedding breakfast will be held on the Thunder Gulch yacht followed by a night of partying at a local nightclub.
