Is Chris Brown a "Silly Boy?"

We're not sure if Rihanna has moved on from her association with Chris Brown , but we think it's awfully suspicious that her new song, Silly Boy, has lyrics like these:

I said I’m not coming back.
You fooled me once but you can’t have that ego turning.
Just too bad for you, that when you had me.
Didn’t know what to do, she’s over you.
'Cause you had a good girl, good girl, girl.
That’s a keeper.
You had a good girl, good girl but didn’t know how to treat her.
So silly boy get out my face.
Why do you like the way regrets taste?

The Los Angeles Times reports that Ri's friend, Kanye West, posted an MP3 version of this song, which also features vocals by Lady GaGa. The track focuses on a girl who won't take her boyfriend back because he's not treating her right. What do YOU think?
