Rihanna went for retro, sexed-up glam by transforming into Marilyn Monroe in her soon-to-release music video for the single, "Pour It Up." 

She donned a skin-baring charcoal blouse, with dark shades and the iconic sun blonde wig that was Monroe's signature. But though her clothes were ultra sexy, her fierce attitude and confidence was striking. 

What was also attention-grabbing is that RiRi wasted no time in taking some layers off, posting a photo of her skimpy, barely-there denim shorts with her behind on full blast, according to the Daily Mail. 

Many say all the shown-off skin is in revenge against ex, Chris Brown, who was recently spotted getting up close and personal with his ex, Karrueche Tran.

But the provocative butt flash could have been apart of a stripper look for the new music clip, featuring women strutting around the pole for dollar bills.

Rihanna was back on the west coast on Monday, posting pictures via Instagram and stirring up excitement on Twitter about the shoot this week.
