Rihanna Goes Topless For Impromptu Photoshoot

Only Rihanna could go topless and look completely glamourous.

After knocking the designer socks off VIP guests at her inaugural Diamond Ball on the weekend, the singer got a bit creative with an impromptu photoshoot that she posted on Instagram.

In the pic, Rih—who is surrounded by her glam squad—pulls her designer gown down to her waist to partly reveal her chest (which she covers up with her arms) while smoking a cigar like a boss.

The "Diamonds" singer captioned the pic, "Thank you to this spectacular team for donating their time and hard work at the #DiamondBall @jennnrosales @yusefhairnyc @melzy917 @mylahmorales @kimmiekyees #iLoveYouGuys #Family !!!"

Earlier that night, the stunning brunette brought down the house with a performance at the charity gala while wearing a voluminous taffeta gown, which she slipped into after sporting a rose-hued Zac Posen gown.

It's been a great week for the singer, who was named brand ambassador and creative director of Puma yesterday.

WWD said she held her "first creative session with the design team, picking out colours, styles and discussing the line’s direction" in Germany yesterday, and this is what she wore (because of course):

the face you make when you the Creative Director of a sportswear company #PUMA
