Rihanna Vs. Porsha Williams? 'RHOA' Star Twerks With 'The Real' Ladies On The Show: Who Twerks Better Porsha's "Stank Walk" Vs. Ri-Ri's "Puppy Tail" Sound Off!! [VIDEOS

Who twerks better? Rihanna or Porsha Williams?

MStars News has learned that both ladies have been shaking their booties over the weekend and into this week. During a appearance on The Real Porsha decided to show fans and the audience what her mama gave her, showing off her "twerk-a-holic ways.

When co-host Adrienne Bailon asked Williams, "what is the most ratchet thing you do," Porsha admitted, "I'm a twerk-a-holic." Tamar Braxton chimed in and said, "Can you show us what you talking about?"

And Porsha didn't turn down the offer. Porsha showed the ladies her "stank walk moves, and twerking ways," as they got in with all the fun action.

Loni Love joked, and said, "we having a 'twerk off."'

In the words of Snoop Dogg and "dropping it like it's hot," Porsha dropped it low when the music dropped. This housewife sure does know how to twerk... and she sure is bootylicious!!!

MStars News also caught Ri-Ri shaking over the weekend while vacationing in her native country of the Barbados. The singer along with her friends got down and dirty at at local bar after what appears they had too many "rum punches."
