Before Rihanna and Ke$ha's Last Girl on Earth tour kicks off on July 4, we e-mailed our pen pal RiRi (yep, we're on e-mailing terms) to pick her brain about a few important topics. Read on to get the dirt on Katy Perry's bachelorette party and her answer to the eternal question: Bieber or JoBros?

Wonderwall: So tell us where you're headed on your new tour with Ke$ha.

Rihanna: We will be going all over the country and into Canada for a few shows. It's a massive tour!

WW: You've won a ton of awards. Which one are you proudest of? Where do you keep them?

Rihanna: My Grammys, of course. I recently purchased a new home, so I have picked out a very special place for them in there!

WW: The Jonas Brothers or Justin Bieber?

Rihanna: JUSTIN!!!

WW: What are your guilty pleasures?

Rihanna: I love Cheetos and can't get enough of the movie "The Hangover." I am also obsessed with "The First 48" on A&E. Sometimes I can go for hours watching that.

WW: Who is on your iPod these days?

Rihanna: Well, Bob Marley can always be found on my iPod. These days I have Paramore, Jay-Z and Trey Songz just to name a few ;0)

WW: We hear you're planning Katy Perry's bachelorette party. What's in store? Can you give us a hint?

Rihanna: I am not planning her party, but I DO plan to attend. Knowing Katy, I'm sure we are in for a crazy night!
