She's the boss! Rihanna goes topless and smokes a cigar as her entourage cover up in her voluminous couture gown in Diamond Ball photo shoot

As Rihanna hosted her inaugural Diamond Ball, behind the scenes she was conducting her own little photo shoot.

Wearing a stunning Zac Posen gown in midnight blue, the Grammy-winning singer, 26, showed off it's voluminous skirt that was so big some of her entourage could hide underneath it.

Of course it wouldn't be a Rihanna photo shoot without a little risque, and in one image the Bajan star poses topless with a smoking cigar.

Rihanna protected her modesty with the strategic angle of her arms, as she would no doubt be barred of Instagram again if she freed her nipples.



She captioned the picture: 'Thank you to this spectacular team for donating their time and hard work at the #DiamondBall'.
In another black and white image she can be seen leaning back seductively on one friend while another caresses her chest.



Stunning: The dress was from Zac Posen's Resort 2015 collection and is called the Midnight Blue Duchesse and Taffeta Strapless Ball Gown

Create some drama in a Zac Posen gown

Wow. This is the kind of dress little girls' dreams are made of. And some grown up girls too.

Rihanna really outdid herself last night at her inaugural Diamond Ball in two Zac Posen gowns that really were fit for a princess. She started the night on the red carpet in a rose coloured, off shoulder dress before switching to this incredible full skirted look from the designer's Resort 2015 collection.

There is so much fabric here with fold upon fold falling beautifully to the floor while the structured bodice cinches Rihanna in at the waist and creates a rather wonderful silhouette. It's hard not to swoon when confronted with such a fairy tale gown.



With her lips shimmering in bright red siren lipstick, the star certainly looked the most glamorous for her event held for The Clara Lionel Foundation.

The Clara Lionel Foundation, a philanthropic organization, was founded in 2012 by the singer in honor of her grandparents, Clara and Lionel Braithwaite.

According to the foundation, its mission is to 'promote initiatives of health, education, arts and culture on a global scale'.
