Rihanna vs. Nicki Minaj: Which Diva Has the Best Booty? – Readers Poll

Rihanna and Nicki Minaj have two of the most famous booties in the music biz. While RiRi's behind isn't as bodacious as Nicki's, whose butt could pretty much rule its own country, the svelte 'Stay' songstress still has quite the rump, perfect for shakin'.

Thanks to the wonders of social media, we've gotten up close and personal with these beautiful ladies' naked behinds, and we want to know: Who do you think has the best butt? Rihanna or Nicki Minaj? We've included some NSFW photos below to help you decide.

Yesterday (May 22), RiRi treated us all to a major booty break, posting an Instagram picture of her robust rump in a pair of.... shorts? If you can even call them that? They more like a denim thong, which we cannot imagine being comfortable in the slightest. Good thing she had ANOTHER thong underneath those things, ya know, to protect her undercarriage from chafing. But enough about chafing, because ew. Just look at that butt! It is truly something to behold.

But what's even more astounding is seeing Nicki Minaj's butt in all of its untamed glory. Back on Valentine's Day 2013, or as Nicki dubbed it, "VAGDAY," the 'Va Va Voom' vixen shared a small collection of Twitter photos of herself in a yellow thong bikini. Even if you're not really into booties, you have to admit, her butt is absolutely extraordinary. How does the Harajuku Barbie even find pants that will fit around those globe-like booty cheeks?

So, whose butt reigns supreme? RiRi's rump or Nicki's booty? Vote below!
