Rihanna has been snapped in a series of saucy lingerie photos after being unveiled as Emporio Armani's "face".

The "Umbrella" singer stripped off for the revealing photos shot in Dublin by Mert and Marcus Piggot.

The lingerie will be available worldwide for Emporio Armani and Armani Jean's spring/summer 2012 collection.

The 23-year-old shows off her enviable shape in lacy lingerie and denim. One shot has her posing on a bed in raunchy silk top and knickers

The Bajan caused controversy by smoking a suspicious-looking cigarette after tweeting from Hawaii with the message: "Kush rolled, glass full...I prefer the better things!"

"Kush" is an American slang term for marijuana and is known as a potent strain of the drug.
