Snapshots: Rihanna & Eminem rehearse for ‘The Monster’ tour...

There's one week to go for Rihanna and Eminem's joint 'The Monster' tour. The two superstars are seen fitting in some final rehearsals for their stadium shows. The three-city trek will see the pair making stops next month in Eminem's native Detroit, Los Angeles, and New Jersey. She also announced that Trapstar teamed up with them for the official tour merchandise. The pair are expected to perform their solo hits and collaborations including 'Love The Way You Lie', 'The Monster' and 'Numb.'
I know a lot of fans are bitter that this tour is pretty reclusive. Bear in mind, Eminem is a father to several teenagers now and he clearly wants to tone things down. Nevertheless, I'm sure they will pull out the stops to make this one memorable. Does anyone know Ri's shoe size? I have to say, her feet look like 'monsters' compared to Eminem's.
