We have a hunch that Rihanna and Miley Cyrus are true weekend warriors. We can only imagine the 25th birthday party RiRi will throw for herself. And Miley Cyrus? With some new photos circulating of the pop princess, not to mention she's been spending quite a bit of quality time with rappers lately, we're betting she is quite the party girl herself.

Let's imagine a typical Rihanna or Miley Cyrus shindig:

Rihanna's takes place in a posh club in either New York City or Los Angeles and RiRi shows up in a barely there outfit. The guest list includes Chris Brown and Katy Perry. We can only imagine the shenanigans that will go on behind closed doors at this rager.

On the other hand, Miley's soiree could be a definite Nashville party or perhaps take place in L.A., where she resides most frequently. The likes of Kelly Osbourne, Demi Lovato, Taylor Swift, Pharrell Williams and Meek Mill will all be invited. And you better believe there will be strippers and a penis cake.

So which is it? Vote below.
