Rihanna played with her wavy strands as she sauntered on stage, sporting a pair of large sunglasses and a tight black tank top.

The hit-maker exhibited her styling prowess when she took the stage, her neck dripping with long and sparkling necklaces that fell past her cleavage. 

Complementing her complexion was an application of winged eyeliner, and deep purple red lips to add to the sexy look.

Having recently unveiled a brand new pair of shoes for Puma, Rihanna's professional life is clearly going from strength to strength.

But it is her romance with Travis Scott that has also made headlines.

The cool couple appeared to confirm that they're more than friends when they put on a steamy display at a recent New York Fashion Week party.

Rihanna sparked further rumours as she cast new love interest Travis as her co-model for her collection with Puma, where she has been named women's creative director. 

'Travis and Rihanna are dating, officially...It's already very serious. He's very into her,' a source told E! on Sunday.
