The bride: Sienna Miller
The groom: Rhys Ifans
Expected celebrity guests: Kate Moss, Jude Law, Sadie Frost, Noel Gallagher, Keira Knightley, Ronnie Wood, Davinia Taylor
The lowdown: Rhys reportedly proposed to Sienna on three separate occasions before she agreed to become his wife - but wedding plans are now well underway. Latest rumours suggest they're planning to tie the knot on Isla Mujeres, a privately owned island off the coast of Mexico. The reception will take the form of a traditional Mexican fiesta, complete with food shipped over from nearby Cancun, washed down with local tequila.
Look out for... Dodgy-looking characters in rowing boats, with long camera lenses poking out from beneath their sombreros. Word is Sienna and Rhys won't be allowing any celebrity magazines to cover the nuptials so the paparazzi will have to go undercover.
