Better than Lady Gaga?!

Sooooo at the beginning of the summer, this hott dance song was leaked called Silly Boy that supposedly featured Lady Gaga and RiRi. Everyone was up in arms about how the song was a diss-track against Chris Brown because of lyrics like "you had a good girl but you didn't know how to treat her" and "silly boy get out my face don't you like how regret tastes", etc. However, Kanye's blog mentioned that Rihanna and Lady Gaga contacted him saying they weren't the singers on the track. Just who is the mystery singer?! : Eva Simons. She's a true rockstar. Period. I think she would give Gaga a hard 'run for her money' if she had the chance. Dare I say she's better than Lady Gaga! Whachu think!?
