Singer-turned-designer Victoria Beckham will design friend and actress Eva Longoria's wedding dress.

The 41-year-old fashion designer has been asked to create the former "Desperate Housewives" actress' bridal gown when she and fiancé Jose Antonio marry next summer, reports mirror.co.uk.

A source said: "Posh (Victoria) is keen to expand the wedding dress side of the business, so it's a dream come true for her to land this gig.

"She knew she was doing it before Jose even proposed."

Longoria, 40, was previously married to American soap actor Tyler Christopher, then French basketball star Tony Parker, and is now set to wed the Mexican TV boss in 2016, much to the delight of Beckham.

"Eva's wedding photographs will be seen all over the world, so it'll be perfect publicity for Posh," the insider added.
