Rihanna and Chris Brown arriving at his 19th birthday bash at Rebel last night!  Is Chris showing Rihanna what he wants to do to her for his birthday???  I’m so bad.  What I really don’t understand is why some people are making a stink about the “age difference” – she turned 20 in February, and he just turned 19, so it’s really not a big deal… I just wish they would stop living in denial!
