Beyonce Knowles "vamped it up" in a campaign for her latest fashion collection.
The 'Halo' singer - who runs label Dereon with her mother Tina - showed off her wild side in the biker-themed shoot as promoted the firm's winter range.
With dramatic eye make-up and a peroxide blonde wig, Beyonce is almost unrecognisable in the provocative pictures, taken by celebrity photographer Tony Duran and styled by her mother.
A source said: "Beyonce vamped it up for these pictures. It's her own clothing line and she wanted to go a bit wild with a biker-themed photo shoot. The clothes are figure hugging and sexy and she wanted the adverts to mimic that."
Beyonce has described the look as "1960s pinup girl meets futuristic biker chick".
The star also stripped naked under a duvet to promote the line's latest looks, which include dramatic studded leggings, lace biker shorts and high waisted hot pants.
The sexy singer - who poses on a motorbike in some of the pictures - can also be seen sporting a series of tattoos, including a large spider web on her left thigh.
The name Dereon was taken from Beyonce's grandmother Agnez Dereon.
Dereon is the second fashion line the singer has developed with her mother, the other is titled House of Dereon
