Last month, MuuMuse hosted the Photographs: Rihanna’s Last Girl On Earth Tour Photo Contest to celebrate the European leg of Rihanna’s latest tour.

Now, Riri’s back in the States.

For a complete list of tour dates for the American leg of the Last Girl on Earth Tour, click here.

For one lucky Muuser and a friend however, the wait is already over.

MuuMuse is proud to be giving away ONE PAIR of tickets to attend Rihanna’s concert at the Staples Center in Los Angeles on Wednesday, July 21st, courtesy of LiveNation.

This time, I don’t want to see photos–I want to hear directly from YOU!

To enter to win, send me an e-mail with the subject line “RIRI” telling me why you deserve these tickets.

Do you have a physical copy of every one of her singles in chronological format framed on your wall? Do you make your mother listen to Rated R everyday? Have you made your own homemade “Rude Boy” tee? (Oh, wait…)

Convince me and these tickets are yours.

One lucky winner will be selected and notified at 12 p.m. EST on July 15.

That’s only one week, so enter now!
