Riri will replace actress Megan Fox in the campaigns, although the brand will continue to use Fox for their beauty campaigns.
The a/w 2011/12 advertising was shot on location in New York and will hit billboards round the world in September. Sadly no images have been released yet so we're looking at Megan Fox's previous Armani pics and trying to mentally swap out her tattoos for Rihanna's!
This won't be the first luxury label to take advantage of the singer's flawless complexion and fabulous figure, though - she previously worked with Gucci for their Tattoo Heart Collection.
Are you looking forward to the change of face? Let us know!
