After posing in 2011's one of the sexiest advertising campaigns, Rihanna has once again shed her clothes for Armani. She has seductively shot a series of black and white pictures in the latest lingerie line.

The 23-year-old singer can be seen flaunting her perfect figure in lacy lingerie collection. In one picture, the singer is lying on a bed in bra and knickers with one hand tucked behind her head and other resting on her hips.

In another shot, she tousles with her hair posing in satin negligee and knickers set. In other shots, she can be seen posing in shorts and denims.

In the last advert for the brand, she had sported blonde locks, however, this time she has kept her hair dark.

The Umbrella singer has surely made it hard to decide which of the two ad campaigns is hotter.

After holidaying in Barbados, the dark beauty is currently off to Hawaii.
